| Abstract: | A formalism based on the coupled channel Born approximation is presented. The treatment is applied to the study of weak direct processes in permanently deformed nuclei coexisting with the rotational excitations.The central idea consists in replacing the coupled-channel wave functions for the relative motion by the waves generated by an angle dependent S-matrix formalism. The resultant approximation is applied to vibrational excitations of deformed nuclei. Numerical results are shown for the excitation of the 3− state in 150Nd by 70.4 MeV 12C, and comparisons with coupled channels calculations are made. |
