Investigation of the excited states of 11B in interactions with alpha particles

Abstract

The elastic and inelastic scatterings of α-particles were investigated at an energy of 29 MeV with excitation of lowlying states of the 11B nucleus. As a result of research we obtained new experimental data for the α + 11B inelastic scattering one leading to the 2.12 MeV (1/2- ), 4.44 MeV (5/2- ) and 6.74 MeV (7/2- ) excited states of 11B nucleus. In the framework of Modified diffraction model, the root mean square radii of these excited states are calculated. The theoretical calculations for the concerned excited states were performed using the coupled channel (CC) method.
