Title: Four-body calculation of the 0/sup +/-1/sup +/ binding energy difference in the A = 4. lambda. hypernuclei

Abstract

The coupled, two-variable integral equations that determine the /sub ..lambda..//sup 4/He and /sub ..lambda..//sup 4/H ground and first excited states, when the NN and ..lambda..N-..sigma..N interactions are represented by separable potentials, are solved numerically. We find the spin-isospin suppression of the ..lambda..-..sigma.. conversion due to the composite nature of the /sup 3/He, /sup 3/H nuclear cores to be a significant factor in understanding the 0/sup +//sup -/1/sup +/ binding energy difference.
