Binding energy of double (Lambda) hypernuclei in the relativistic mean field theory

摘要

The binding energy of two (Lambda) hyperons bound to a nuclear core is calculated within the relativistic mean field theory. The starting point is a two body relativistic equation of the Breit type suggested by the RMFT, and corrected for the two-particle interaction. The 2 (Lambda) correlation energy is evaluated and the contribution of the (delta) and (phi) mesons, acting solely between hyperons, to the bond energy (sigma)B(sub (Lambda)(Lambda)) of ((sub (Lambda)(Lambda)))(sup 6)He, ((sub (Lambda)(Lambda)))(sup 10)Be and ((sub (Lambda)(Lambda)))(sup 13)B is calculated. Predictions of the (Delta)B(sub (Lambda)(Lambda)) A dependence are made for heavier (Lambda)-hypernuclei. (K.A.) 32 refs.
