Low-lying quadrupole collective states of the light and medium Xenon isotopes

TL;DR

This paper models the low-lying quadrupole collective states of light and medium Xenon isotopes using a microscopic approach based on the Generalized Bohr Hamiltonian and Woods-Saxon mean fields, achieving close agreement with experimental spectra.

Contribution

It introduces a fully microscopic calculation of Xenon isotopes' spectra without fitting parameters, using the GBH with Woods-Saxon mean fields.

Findings

Theoretical spectra closely match experimental data.

Microscopic approach successfully describes low-lying collective states.

Parameter-free calculations demonstrate model robustness.

Abstract

Collective low lying levels of light and medium Xenon isotopes are deduced from the Generalized Bohr Hamiltonian (GBH). The microscopic seven functions entering into the GBH are built from a deformed mean field of the Woods-Saxon type. Theoretical spectra are found to be close to the ones of the experimental data taking into account that the calculations are completely microscopic, that is to say, without any fitting of parameters.
