I. Kumagaifuse et al., EVIDENCE FOR A CENTRAL REPULSION POTENTIAL FROM PIONIC DECAY OF S-SHELL LAMBDA-HYPERNUCLEI, Physics letters. Section B, 345(4), 1995, pp. 386-392
Pionic decays of A = 4 and 5 hypemuclei are discussed for obtaining in
formation about the nucleus-Lambda potential. The results for the avai
lable decay widths support as a whole the notion that the nucleus-Lamb
da potential has a central repulsion not only in A = 5 but also in A =
4 hypernuclei.
