The Gamow-Teller (GT) unit cross section, σ̌GT, is an essential quantity to deduce the GT transition strength, B(GT), from the (p, n) 0°cross section. (p, n) measurements at 200 and 300 MeV were performed using the Neutron Time-of-Flight (NTOF) facility at the Research Center for Nuclear Physics (RCNP). The σ̌GT values were determined, for the first time, for several nuclei in the region of A > 50 at E p = 200 and 300 MeV. A significant difference between the B(GT) values obtained by (p, n) and (3He, t) measurements was found.
