摘要
The level structure of 91Zr has been investigated by inelastic proton scattering at 18.7 MeV. Angular distributions were obtained for the excitation of 19 levels in 91Zr. The results for the low-lying states, seen strongly in the 90Zr(d, p) reaction, were compared to distorted wave calculations using shell model form factors for the excitation of the odd neutron beyond the closed shell of 50. The resulting depth of the interaction potential indicated a relatively strong core excitation admixture for these states. Calculations using more complicated wave functions gave better results especially if core polarization effects were included. At higher excitation energies the six states resulting from the coupling of the d 5 2 neutron to the 3- excited state of 90Zr were observed. The cross sections were consistent with the predictions of the weak coupling model. © 1969.
