Study on the low-lying collective states of A=54-124 nuclei in 50 MeV α-particle scattering and in the 64Ni(3He, 3He') reaction by DWBA and coupled channel method

The analysis of elastic and inelastic scattering of α particles with energy of 50 MeV by nuclei with mass numbers A=54-124 and of 3He particles by the nucleus 64Ni is given in the framework of the optical model. The parameters of multipole deformations for lower states are determined. The parameters for quadrupole and octupole deformations of the potential for the nucleus 112Sn are extracted, the values of the hexadecupole deformation β4 of the potential for nuclei 94Zr, 120,124Sn are found. Information is extracted on the ratio of deformation parameters for the neutron and proton components in lower collective states (21+, 31-) of nuclei with A=90-124
