    Phase shift analysis of p12C scattering at energies 0.2-1.1 MeV
    (Azerbaijan National Academy of Sciences Institute of Radiation Problems ve Turkish Atomic Energy Authority, 2006) Dzhazairov-Kakhramanov, A. V.; Dubovichenko, S. B.; Bölüm Yok
    The experimental data of cross-sections of nuclear reactions and their analysis within the frames of various theoretical models are the major source of information about nuclear structure, nature and mechanism of nuclear-nuclear (cluster-cluster) interaction. Researches in nuclear astrophysics are more complicated since in many cases only theoretical predictions can supply deficient experimental information on characteristics of nuclear reactions. This difficulty results from low energy of interraction in substance matter of stars which equals from tenth to tens keV and thus, there is no possibility of direct cross-section measurments which are required in astrophysical caculations of nuclear reactions. Generally, cross-section measurments are carried out at higher energies (about hundreds of keV) and then they are extrapolated into the energy range representing interest for nuclear astrophysics.

    Phase shift analysis of the elastic p12C scattering differential cross sections at astrophysical energies
    (Azerbaijan National Academy of Sciences Institute of Radiation Problems ve Turkish Atomic Energy Authority, 2006) Burminsky, V. P.; Burtebayev, N.; Chechin, L. M.; Dubovichenko, S. B.; Jazairov-Kakhramanov, V.; Zazulin, D. M.; Bölüm Yok
    Using the earlier obtained experimental data on the p12C elastic scattering at the energies Ec.m. = 213, 317, 371, 409, 422, 434, 478, 689, 900, 1110 keV and in the range of angles Ɵlab. = 10° - 170° the phase shift analysis has been made and the interaction potential of the p12C system in S- state has been constructed. The standard optical model analysis of the angular distributions has also been carried out.
