研究了较高自旋(i=10({Dirac_h}/2{pi}))和16.64 MeV激发能的核{sup 34}S。将数据与不同的壳模型计算进行了比较，其中使用了两个主要壳-SD和FP-的有效相互作用。在N{Ne}Z核中，首次观察到等标量(T=0)质子-中子对在高自旋时对FP壳层的促进作用。
The nucleus {sup 34}S has been studied up to relatively high spin (I=10({Dirac_h}/2{pi})) and up to an excitation energy of 16.64 MeV. Data are compared with different shell model calculations where effective interactions involving two main shells, the sd and the fp, are used. For the first time in an N{ne}Z nucleus, it is observed that the promotion of an isoscalar (T=0) proton-neutron pair to the fp shell becomes energetically favored at high spin.
