Hyperon halo structure of C and B isotopes

We study the Lambda hypernuclei of C and B isotopes by the Hartree-Fock model with Skyrme-type nucleonnucleon and Lambda-nucleon interactions. The calculated Lambda binding energies agree well with the available experiment data. We found halo structure in the Lambda 1p state with extended wave functions beyond the nuclear surface in the light C and B isotopes. We also found the enhanced electric-dipole transition between Lambda 1p and is states, which could be the evidence for this hyperon halo structure.

Automated summary

The study indicates that the calculated Lambda binding energies agree well with experiment data, and a halo structure is found in the Lambda 1p state of light C and B isotopes with extended wave functions beyond the nuclear surface. Enhanced electric-dipole transition between Lambda 1p and is states is observed, potentially serving as evidence for the hyperon halo structure.
