FIELDS, PARTICLES, AND NUCLEI

Neutron Rich Hypernuclei in Chiral Soliton Model

V. B. Kopeliovich

Institute for Nuclear Research, Russian Academy of Sciences, Moscow

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, $A=B\leq\sim 10$. 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 $^8_\Lambda He$ and recently discovered $^6_\Lambda H$ satisfactorily agree with data. Hypernuclei $^7_\Lambda$H, $^9_\Lambda$He are predicted to be bound stronger in comparison with their nonstrange analogues $^7$H, $^9$He; hypernuclei $^{10}_\Lambda $Li, $^{11}_\Lambda $Li, $^{12}_\Lambda $Be, $^{13}_\Lambda $Be etc. are bound stronger in the nuclear variant of the model.
