用谱分布理论研究FP壳层核的同位旋不守恒

Isospin nonconservation for fp-shell nuclei by spectral distribution theory

Kamales Kar, Sukhendusekhar Sarkar

摘要:

在用谱分布理论计算fp壳层核基态能量时,考虑了一加二体同位旋非守恒核相互作用。这反过来又被用来计算等压质量多重态方程中的线性项,然后将预测值与添加库仑贡献后的实验值进行比较。该协议被认为是合理的观察sd壳核较早。人们还可以看到,在这种方法中,对线性项的贡献几乎完全来自单体等矢量哈密顿量,这导致了问题的极大简化。

英文摘要:

The one- plus two-body isospin nonconserving nuclear interactions are included in the prediction of ground state energies of fp shell nuclei using spectral distribution theory. This in turn is used to calculate the linear term in the isobaric mass-multiplet equation and the predictions are then compared to experimental values after the addition of the Coulomb contribution. The agreement is found to be reasonable as observed for sd shell nuclei earlier. One also sees that in this method the contribution to the linear term comes almost completely from the one body isovector Hamiltonian and that results in a huge simplification of the problem.
