摘要

【正】 Based on the ΛΛα model,a variational calculation for the double-Λhypernucleus _ΛΛ⁶He is carried out with the harmonic oscillator formalism.Among thevarious Λ-Λ interactions proposed,the Gaussian type with or without repulsive core ischosen.Their influence on eigenenergy,structure and interparticle correlation is studiedby observing the shape-density.
