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 Λ hyperon in an 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.
