Experimental study of Gamow-Teller transitions via the high-energy-resolution ¹⁸O(³He, t)¹⁸F reaction: Identification of the low-energy "super"-Gamow-Teller state

NUCLEAR REACTIONS ¹⁸O(³He, t)¹⁸F, E=140 MeV/nucleon; measured E(t), I(t), angular distribution of tritons using Grand Raiden magnetic spectrometer at RCNP facility. ¹⁸F; deduced levels, J, π, L-transfers, widths, B(GT) Gamow-Teller strengths, low-energy super Gamow-Teller (LeSGT) state. DWBA analysis. Comparison with previous experimental and evaluated data, and with shell-model calculations using USDA, USDB and modified-PSDWBT interactions, and quasiparticle-random-phase approximation (QRPA) calculations.
