摘要

摘要: 近年来 ,在7ΛLi超核γ谱学实验中 ,通过基态二重态间自旋翻转M1跃迁能量的测定 ,为ΛN自旋自旋相互作用强度提供了重要的信息 ;通过对约化跃迁几率B(E2 ;7ΛLi 5 / 2 + → 1/ 2 + )的测定 ,表明7ΛLi中的6Li核心比自由空间中6Li核要小 ,Λ超子的胶样作用引起了7ΛLi核的收缩 . The recent progress in gamma-ray spectroscopy of hypernuclei is described. The spin-flip M1 γ transition between the ground-state spin doublet of 7 ΛLi has been observed. The transition energy provides crucial information on the strength of the spin-spin intetraction between Λ and nucleons. The experimental result of B(E2; 7 ΛLi 5/2 +→1/2 +) gives evidence that the size of the 6Li core in 7 ΛLi is smaller than that for the 6Li nucleus in the free space, indicating that the...
