Proton drip line of deformed hypernuclei

TL;DR

This paper investigates how adding a hyperon affects the proton drip line in deformed hypernuclei using a Skyrme-Hartree Fock approach, revealing that p-state hyperons can extend the drip line.

Contribution

It introduces a detailed analysis of hyperon effects on the proton drip line in deformed nuclei within a Skyrme-Hartree Fock framework, highlighting deformation's role.

Findings

P-state hyperons can extend the proton drip line in some cases.

S-state hyperons do not extend the drip line.

Deformation influences the hyperon-induced extension of the drip line.

Abstract

The proton drip line of (hyper)nuclei is examined within the framework of the deformed Skyrme-Hartree Fock approach by adjusting the nuclear force parameters to exactly reproduce the core binding energies. The impact of adding a {\Lambda} hyperon in a s or p state is studied, and it is found that in some cases the deformation effect facilitates the extension of the drip line by an added p-state hyperon. However, no extension of the drip line is found for s-state hypernuclei.
