Abstract
The spin and isospin dependent part of the nuclear effective interaction is studied using the experimentally known Gamow-Teller states in 48Ca, 90Zr and 208Pb. About half of the strength of the residual interaction in the nucleon-nucleon channel can be expounded by the correlated π + ϱ exchange potential. Also, the corresponding interaction in the delta-nucleon channel is investigated and a reasonable agreement with the observed qunchiing of the Gamow-Teller strength is obtained.
