Abstract
The Landau-Migdal parameters for nucleon-nucleon (g'_NN) and nucleon-\Delta (g'_N\Delta) couplings are estimated from recent experimental data on the giant Gamow-Teller state of 90Nb. The observed quenching of the GT strength by 10% provides 0.16<g'_N\Delta<0.23 for g'_\Delta\Delta <1.0, while the excitation energy g'_NN\sim 0.59. The critical density of pion condensations is much lower than those previously discussed with the universality ansatz.
