The purpose of this work is to study the problems of ecological education under the conditions of the transition to a green economy. The new economic reform changesthe labor market. There is a huge gap between the demand of the labor market and the higher education system. The transition to a green economy requires new work places, new professions, new competencies and green skills. In Kazakhstan there are a number of problems for the transition to a green economy, conditioned by a deficit of competence, skills and specialists. The education system is actively developing ecological competence of future specialists. The need for a professional individuality of the future specialists with high ecological competence, professional competence, able to solve ecological problems independentlyexpresses the actuality of the problem of finding a solution.

The main aim of this work was to describe the reactions of elastic scattering of 16O + 12C over a wide range of energies in an optical model with an l-dependent core. We obtained a value for the compress- ibility coefficient that agreed with the one found from data on the giant monopole resonance. We considered the elastic transfer of an α particle to reproduce the cross section in the reverse hemisphere. © 2011 Allerton Press, Inc.

The angular distribution for the elastic scattering of 16O, 14N and 12C on 27Al was measured at an energy of 1.75 MeV per nucleon in the DC-60 INP NNC (Institute of Nuclear Physics, National Nuclear Centre) cyclotron located in Astana in order to study the elastic scattering mechanism in these nuclear systems. The experimental results were analyzed with the help of the optical potential code SPI-GENOA. Good agreement between the experimental data and the theoretical calculations was obtained by using suitable optical potential parameters. The elastic scattering of 16O, 14N and 12C on 27Al does not reveal any unusual features or threshold anomaly at this energy. © 2011 The Royal Swedish Academy of Sciences.

The aim of this work is to study the elastic transfer phenomenon which takes place in the elastic scattering of 16O on 12C at energies near the Coulomb barrier. Where, the angular distribution decrease steadily with increasing the scattering angle, then the cross section will increase at backward angles due to the α-transfer process. This reaction was also studied at different energies for tracking the nuclear rainbow phenomenon. The experimental data of the angular distribution at these energies were compared to the calculation predictions. The optical potential codes such as SPIVAL and Distorted Wave Born Approximation (DWUCK5) were used in analysis.

the elastic scattering of protons, deuterons and 3He on 6Li at different incident energies have been analyzed in the framework of the optical model using ECIS88 as well as SPI GENOA codes. The potential parameters were extracted in the phenomenological treatment of measured by us angular distributions and literature data. A good agreement between theoretical and experimental differential cross sections was obtained in whole angular range. Parameters for real part of potential have been also calculated microscopically with singleand double-folding model for the p and d, 3He scattering, respectively, using DFPOT code. For best agreement with experiment the normalization factor N for the potential depth is obtained in the range of 0.7-0.9.

The measurement of the angular distribution for the elastic scattering of 16O, 14N and 12C on 27Al has been done at energy 1.75 MeV/nucleon. The optical potential code SPIVAL used in this work to analyze the experimental results. A good agreement between the experimental and theoretical results was obtained.

An experiment was performed with a 24.5 MeV 14N beam on a 12C target in the cyclotron DC-60 located in Astana, Kazakhstan, to study the elastic scattering of 14N on 12C; the scattering was also analyzed at different energies for tracking the phenomenon of remarkable structure at large angles. Its aims were to extend the measurements to very large angles, and attempt to uniquely identify the elastic scattering potential. Good agreement between the theoretical and experimental data has been obtained with suitable optical potential parameters. Optical model calculations with l-dependent imaginary potentials were also applied to the data and relatively good agreement was found.

Optical model analysis has been conducted for the elastic scattering of 1p-shell nuclei around the Coulomb barrier energies. We have used both microscopic double-folding and phenomenological potentials for the real part of the complex nuclear potential. The imaginary potential has the shape of phenomenological Wood-Saxon volume. The case 14N+12C for 1p-shell nuclei has been studied in detail and it is noticed that a large normalization of the strength of the double-folding real potential is needed to explain the structure observed in the experimental data. A good agreement between experimental data and theoretical results is obtained for the phenomenological potential case. © Published under licence by IOP Publishing Ltd.

The elastic scattering of the 20Ne+16O system has been analyzed with a phenomenological potential approach within the framework of the optical and coupled-channels models at E Lab =50.0 MeV. The striking feature of the experimental data is the oscillatory structure at the intermediate angles and a rapid increase at large angles. Optical potentials have difficulty in describing such structures and predict a fall of experimental data around the intermediate angles. In order to explain this structure, we have used a deep real potential with a sum of Woods-Saxon typed surface and volume imaginary potentials. We present that deep real potential with these imaginary potentials explain the oscillatory structure and backward rise observed in the elastic scattering data within both models. It should be pointed out that there is a magnitude problem of the inelastic 2+ data for the deformed 20Ne nucleus that the standard coupled-channels model is unable to predict correctly. © Published under licence by IOP Publishing Ltd.

The aim of this work is to track the phenomenon of α-cluster transfer mechanism at low energies 1.25, 1.5 and 1.75 MeV/n, close to the Coulomb barrier energy for 12C(16O,(12C)16O and 16O(12C,(16O)12C nuclear systems. The measurements of the angular distribution show a significant increase in the differential cross section at large angles due to alpha-transfer mechanism. The optical model code SPI-GENOA could be used effectively for fitting the experimental data with the theoretical predictions nearly up to angle 90°, where the differential cross section decreases steadily with increasing the scattering angle. For the second hemisphere, at angles greater than 100°, there is a large increase in cross section due to the contribution of α-transfer mechanism, and the Distorted Wave Born Approximation (DWBA) method could be used effectively for fitting the experimental data with the theoretical predictions at this region using (DWUCK5) code. © 2011 Elsevier B.V.
