$\mathrm{\Lambda }$ hyperonic effect on the magnesium dripline

Neutron dripline calculations for both magnesium nuclei and magnesium + $\mathrm{\Lambda }$ hypernuclei have been carried out in a microscopic framework using a chiral effective model. The results are compared with two other relativistic mean field models, SPL-40 and NL3. All three models describe the $\mathrm{\Lambda }$ separation energy of known hypernuclei adequately. The extrapolation to the driplines for moderately heavy hypernuclei are found to be strongly model-dependent.
