用高分辨激光光谱学研究了直到N=82壳层闭合的镉的富中子同位素。214.5 nm处的深紫外光激发和辐射束聚束提供了所需的实验灵敏度。首次在(127)Cd和(129)Cd中观察到长寿命的异构体。球壳模型的一个基本特征明确地被11/2(-)四极矩的线性增加所证实。值得注意的是，这种机制被发现远远超出了h(11/2)壳层。
The neutron-rich isotopes of cadmium up to the N=82 shell closure have been investigated by high-resolution laser spectroscopy. Deep-uv excitation at 214.5 nm and radioactive-beam bunching provided the required experimental sensitivity. Long-lived isomers are observed in (127)Cd and (129)Cd for the first time. One essential feature of the spherical shell model is unambiguously confirmed by a linear increase of the 11/2(-) quadrupole moments. Remarkably, this mechanism is found to act well beyond the h(11/2) shell.
