| Abstract: | The high spin states of 162Yb and 164Hf have been studied using 122Sn(44Ca, 4n) and 120Sn(48Sn(48Ti, 4n) reactions respectively. The resulting new level schemes for 162Yb and 164Hf are presented and compared with existing data for 160Er. The systematic behaviour of these three N = 92 isotones at large angular momentum yields information both on modifications of the single-neutron spectrum of states resulting from the polarisation of the nuclear field and on the single-proton spectrum of states. |
