Lifetimes of states in the negative-parity band, based on the \(\nu (h_{11/2})\) orbital in \(^{103}\hbox {Pd}\), have been measured in the spin range from 27/2 to 39/2 using the Doppler-Shift Attenuation Method. The inferred B(E2) values are observed to decrease with increasing angular momentum and \({\mathcal {J}}^{\text {(}2\text {)}}/\)B(E2) values are found to be large (> 300 \(\hbar ^2\hbox {MeV}^{-1}\hbox {(eb)}^{-2}\)). These observations along with calculations based on the semiclassical particle-rotor model approach suggest that antimagnetic and collective rotation, along with gradual neutron alignment are responsible for angular momentum generation in the band under consideration.

基于自旋范围内的\（^ {103} \ hbox {Pd} \）中的\（\ nu（h_ {11/2}）\）轨道，在负奇偶校验带中的状态的生命周期已被测量。使用多普勒频移衰减方法从27/2到39/2。所推断出的乙（ë 2）观察值随角动量，并降低\（{\ mathcal {Ĵ}} ^ {\文本{（} 2 \文本{）}} / \）乙（ë 2）的值是被发现很大（> 300 \（\ hbar ^ 2 \ hbox {MeV} ^ {-1} \ hbox {（eb）} ^ {-2} \））。这些观察结果以及基于半经典粒子转子模型方法的计算结果表明，在所考虑的频带中，反磁和集体旋转以及逐渐的中子对准是导致角动量产生的原因。
