Abstract
The Gamow-Teller strength function including all 2p2h states with excitation energy up to 4 ħω is calculated for the 48Ca(p, n) 48 Sn reaction. A detailed discussion on the treatment of the self-energy term in connection with the non-energy-weighted sum rule is presented. The quenching of the Gamow-Teller strength in the low-lying region may chiefly be explained by the tensor correlation, and partly by some vertex corrections due to the Δ-hole and other exchange currents.
