【摘要】 本文用双位阱壳模型投影交分方法对~6Li基态进行计算.计算说明,~6Li基态中氘的方均根半径比自由氘核的方均根半径小;随着氘核集团同a集团的平均间距的减小,氘核集团表现出先压缩而后稍膨胀的压缩效应和先呈扁形而后呈拉长形的变形效应.计算初步地说明了,核力的奇宇称态排斥分量和集团间核子的包利交换效应,无论在~6Li基态的集团结构中和氘核集团的压缩和变形效应中都起着重要作用.更多还原

【Abstract】 The ground state of ~6Li is investigated by means of the projected variational method for double well-cluster shell model. The results of the variational calculation show that the root-mean-square radius of d-cluster in the ground state of ~6Li is smaller than that of free deuteron and as the mean distance between the a-cluster and the d-cluster decreases there are two effects on the d-cluster, namely contraction effect in which the d-cluster contracts first and then makes a bit extension and deformation effect in which the d-cluster makes oblation first and then streteches.It is also demonstrated by the calculation that the repulsive component of the odd sytate of N-N force and the pauli exchange of the nucleons between the clusters play an important role not only on the cluster structure in the ground state of ~6Li but also on the contraction and the deformation of d-cluster in ~6Li.更多还原
