Abstract

   Chaotic features of nuclear energy spectrum in 68Ge nucleus are investigated by nuclear shell model. The energies are calculated through doing shell model calculations employing the OXBASH computer code with effective interaction of F5PVH. The 68Ge nucleus is supposed to have an inert core of 56Ni with 12 nucleons (4 protons and 8 neutrons) move in the f5p-model space ( and ). The nuclear level density of considered classes of states is seen to have a Gaussian form, which is in accord with the prediction of other theoretical studies. The statistical fluctuations of the energy spectrum (the level spacing P(s) and the Dyson-Mehta (or statistics) are well described by the Gaussian orthogonal ensemble (GOE). Furthermore, these fluctuations are independent on the spin J.
用核壳模型研究68Ge核能谱的混沌特征
利用核壳模型研究了68Ge核能谱的混沌特征。在F5PVH的有效相互作用下,利用OXBASH计算机程序进行壳层模型计算,计算能量。68Ge核应该有一个56Ni惰性核,有12个核子(4个质子和8个中子)在f5p模型空间(和)中运动。所考虑的状态类的核能级密度具有高斯形式,这与其他理论研究的预测一致。高斯正交系综(GOE)很好地描述了能谱的统计波动(能级间距P(s))和Dyson-Mehta(或统计量)。此外,这些起伏与自旋J无关。
