奇质量核最低激发态的一种推广近似

An Extended Approximation for the Lowest-lying States in Odd-mass Nuclei

S. Mishev, V. V. Voronov

摘要:

本文提出了一个基于扩展玻色子近似的奇质量核最低激发态的增强模型。我们的方法是建立在准粒子声子模型,扩展它考虑到基态相关由于泡利原理的作用,比传统的理论更准确。在这个模型中的准粒子和声子之间的相互作用强度依赖于明确耦合的奇质量核方程的奇偶核的准粒子占据数。在这个模型中,我们用A $\approx$ 130计算了几种Te、Ba和Ba同位素的跃迁几率。

英文摘要:

An enhanced model, based on the Extended Boson Approximation, for the lowest-lying states in odd-mass nuclei is presented. Our approach is built on the Quasiparticle Phonon Model, extending it to take into account the ground state correlations due to the action of the Pauli principle more accurately than in the conventional theory. The derived interaction strengths between the quasiparticles and the phonons in this model depend on the quasiparticle occupation numbers explicitly coupling the odd-mass nucleus equations with those of the even-even core. Within this model we calculated the transition probabilities in several Te, Xe and Ba isotopes with A$\approx$130.
