| 中文摘要 | High spin states in /sup 134/Ce nucleus have been studied by using the heavy-ion induced reaction /sup 122/Sn(/sup 16/O,4n) carried out at China Institute of Atomic Energy. The early level scheme has been extended with spin up to 22 h . However, our result is different from that in a recent publication, and the magnetic rotation bands reported there have not been confirmed. Our observed level structures may be interpreted as shape coexistence. The 10/sup +/ state at the backbending with h/sub 11/2/ quasineutron configuration has an oblate deformation with an asymmetry parameter gamma ap -60 degrees (Lund convention), and the 10/sup +/ isomer is a yrast trap of prolate deformation with gamma ap -120 degrees , whereas the other signature partner bands with h/sub 11/2/ and g/sub 7/2 / proton configuration probably have a prolate deformation with gamma ap 0 degrees. |
