K 的高自旋态已在聚变蒸发反应 C(Si,)K 中填充，并使用莱尼亚罗国家核研究所先进伽马跟踪阵列的三簇探测器的射线光谱技术进行了研究。已经发现了几种激发能高达 8 MeV 并且自旋向上的态。这些状态根据中子-质子空穴对进行讨论。大模型空间中的壳模型计算与大多数能级的实验数据表现出良好的一致性。这里研究该核结构的演化作为激发能和角动量的函数。
High-spin states ofK have been populated in the fusion-evaporation reactionC(Si,)K and studied by means of-ray spectroscopy techniques using one triple-cluster detector of the Advanced Gamma Tracking Array at the Istituto Nazionale di Fisica Nucleare, Laboratori Nazionali di Legnaro. Several states with excitation energy up to 8 MeV and spin up tohave been discovered. These states are discussed in terms ofandneutron-proton hole pairs. Shell-model calculations in a large model space have shown good agreement with the experimental data for most of the energy levels. The evolution of the structure of this nucleus is here studied as a function of excitation energy and angular momentum.
