中文摘要	High spin states in Ce-134 nucleus have been studied by using the heavy-ion induced reaction Sn-122(O-16,4n) carried out at China Institute of Atomic Energy. The early level scheme has been extended with spin up to 22h. 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(+) state at the backbending with h(11/2) quasineutron configuration has an oblate deformation with an asymmetry parameter gamma approximate to -60degrees (Lund convention),and the 10(+) isomer is a yrast trap of prolate deformation with gamma approximate to -120degrees, whereas the other signature partner bands with h(11/2) and g(7/2) proton configuration probably have a prolate deformation with gamma approximate to 0degrees.
