Probing spin-isospin excitations in proton-rich nuclei via the ¹¹C(p, n)¹¹N reaction

NUCLEAR REACTIONS ¹H(¹¹C, n), E=95 MeV/nucleon; measured reaction products, time-of-flight, En, In, (particle)n-coin, angular distribution; deduced σ(θ), σ(θ, E), cumulative Gamow-Teller transition strengths, B(GT) values to the 1/2^- state at 0.73 MeV and the 3/2^- state at 2.86 MeV in ¹¹N. Multipole decomposition analysis. Comparison to shell-model calculations with wbp interaction and to experimental data on the ¹¹B(n, p), (d, ²He), (t, ³He) reactions. Ursinus liquid hydrogen target coupled to Low Energy Neutron Detector Array (LENDA) and S800 spectrograph. ¹¹C beam produced from Be(¹⁶O, X) reaction and purified with A1900 fragment separator at Coupled Cyclotron Facility (CCF) at the NSCL.
