    Nuclear level density as a tool for probing the inelastic scattering of 6He
    (Institute of Physics Publishing, 2015) Canbula B.; Babacan H.
    The cross sections are calculated for the both elastic and inelastic scattering of 6He from 12C and 4He. A phenomenological optical potential is used to describe the elastic scattering. 4He is taken as spherical and inelastic couplings to the first excited states of 6He and 12C are described with collective rotational model and coupled-channels method. Deformation lengths for 6He and 12C are determined from semi-classical nuclear level density model by using Laplace-like formula for the nuclear level density parameter. The comparison of the predicted and the measured cross sections are presented to test the applicability of nuclear level density model to the light exotic nuclei reactions. Good agreement is achieved between the predicted and measured cross sections. © Published under licence by IOP Publishing Ltd.

    Probing 6He induced reactions with nuclear level density
    (Walter de Gruyter GmbH, 2023) Canbula D.; Canbula B.; Babacan H.
    In this study, both elastic and inelastic cross sections of the light exotic nucleus 6He on 12C and 4He at energies of 18MeV, 30MeV, 3.8MeV, 4.2MeV, 4.7MeV, 5.1MeV, 5.4MeV, and 5.8MeV, as well as the quasi-elastic cross section of 6He on 9Be at 16.2MeV and 21.3MeV, are calculated using the coupled-channel method. The deformation parameters of the first excited states of 6He, 9Be and 12C are obtained through the collective nuclear level density. The results align well with the available experimental data. It is demonstrated that the collective nuclear level density is essential to reduce the uncertainty between the deformation parameter and the optical model parameters. Furthermore, it is shown that the first excited state of both the projectile and the target must be considered in calculations 6He + 9Be scattering at increasing energies. © 2023 Walter de Gruyter GmbH, Berlin/Boston.
