Abstract :
The microscopic effective pairing interaction in the 1S0-channel is investigated for two different values of the chemical potential μ starting from the separable form of the Paris NN-potential. It is shown that, within a good accuracy, this effective interaction can be approximated by the off-shell free T-matrix taken at the negative energy E=2μ.
