Neutron Rich Hypernuclei in Chiral Soliton Model

Abstract
The binding energies of neutron rich strangeness S=-1
hypernuclei are estimated in the chiral soliton approach using
the bound state rigid oscillator version of the SU(3) quantization model.
Additional binding of strange hypernuclei in comparison with nonstrange
neutron rich nuclei takes place at not large values of atomic (baryon) numbers,
. This effect becomes stronger with increasing isospin of nuclides,
and for the "nuclear variant" of the model with rescaled Skyrme constant e.
Binding energies of 8Λ He and recently discovered
6Λ H satisfactorily agree with data.
Hypernuclei 7ΛH, 9ΛHe
are predicted to be bound stronger in comparison with their nonstrange analogues
7H, 9He; hypernuclei 10Λ Li, 11Λ Li,
12Λ Be, 13Λ Be etc.
are bound stronger in the nuclear variant of the model.
