摘要
通过入射能量为１４１ＭｅＶ的（１００）Ｒｕ（（３２）Ｓ，２ｐ２ｎ）（１２８）Ｃｅ反应布居（１２８）Ｃｅ的高自旋态，利用多普勒移动衰减法测量了１６＋态的寿命．相应的Ｂ（Ｅ２）值与理论计算的转动值相当．
The high spin states in 128Ce were populated with the reaction l00Ru (32S,2p2n) 128Ce at an incident energy of 141MeV. The lifetime of the 16+ state was measured by using the Doppler shift attenuation method. The corresponding B(E2) value is compatible with the rotational value of theoretical calculation.
