激发态的布居已达到和5MeV的激发能与(,)反应。在这个核中,已经确定了态的自旋。水平计划相比,壳模型计算使用Universaleffective相互作用和蒙特卡罗壳模型方法。采用全模型空间的计算不能再现观测到的水平。结果表明,在相对较低的激发能量下,需要跨越能隙的激发来实现对数据的描述。将theandorbitals纳入模型空间得到了改进的结果,但表明需要进一步改进的模型,以重现所观察到的光谱。
Excited states inhave been populated toand 5 MeV excitation energy with the(,) reaction. Firm spin assignments for states withhave been made in this nucleus. The level scheme is compared to shell-model calculations using the Universaleffective interaction and the Monte Carlo shell model method. Calculations employing a fullmodel space fail to reproduce the observed levels. The results indicate that excitations across thegap are required at relatively low excitation energy to achieve a description of the data. The incorporation of theandorbitals into the model space gives improved results but indicate the need for further refinement of the models to reproduce the observed spectra.
