Abstract
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...
