Λ－N介子交换势和超核的Λ超子结合能

∧-N MESON EXCHANGE POTENTIAL AND ITS ∧ BINDING ENERGIES IN HYPERNUCLEI

用Λ－Ｎ介子交换势计算的Λ超子结合能，重新确定介于交换势中参数Ｐ，获得改进了的Λ－Ｎ介子交换势．用此改正的Λ－Ｎ势计算Λ－Ｐ弹性散射截面与ｓ波相移以及，，，，，，和中Λ超子的结合能，计算结果和实验值基本符合。

By calculating the ∧ binding energy in He with the ∧-N meson exchange Potential, the parameter p in the potential is redetermined and a modified ∧-N meson exchange potential is obtained.Based on the modified potential, its phase shift of ∧-P elastic scattering,and the A binding energies of hypernuclei Li,Be,B,B,C,N,O and O are calculated,the calculated ∧ binding energies basically agree with the experiments.
