Relativistic Mean-Field Calculation for Hypernuclei

  • The ground state properties of hypernuclei are studied theoretically using the relativistic mean-field theory with TM1 and NL-SH force parameters. It is found that these new parameters can very satisfactorily reproduce the ground state properties of the above hypernuclei. The parameter sets TM1 and NL-SH give a very similar description on the hypernuclei. The properties of hypernuclei in baryon hyperon systems are insensitive to the force parameters of effective nucleon-nucleon interaction. The influence of the pairing force is taken into account in the study of hypemuclei and it is found that it leads to the even-odd effect.

Abstract: The ground state properties of hypernuclei are studied theoretically using the relativistic mean-field theory with TM1 and NL-SH force parameters. It is found that these new parameters can very satisfactorily reproduce the ground state properties of the above hypernuclei. The parameter sets TM1 and NL-SH give a very similar description on the hypernuclei. The properties of hypernuclei in baryon hyperon systems are insensitive to the force parameters of effective nucleon-nucleon interaction. The influence of the pairing force is taken into account in the study of hypemuclei and it is found that it leads to the even-odd effect.
