The g9/2 isobaric analogue resonance (IAR) is located at the excitation energy Ex = 11.139 MeV in 49V through the 48Ti(p, γ)49V reaction, (p, p1γ) angular distributions and the presence of the transition from the resonance to the 2.178-MeV (Jπ = 9/2+) level in 49V arc used to identify this resonance. The analogue–antianalogue M1 transition strength is found to be Γγ(M1) = 0.050 ± 0.009 eV or 0.2% of the single-particle estimate. This reduction in transition strength can be attributed partly to the fragmentation of the analogue and partly to the nonsingle-particle character of the antianalogue state.

Gamma Decay

The resonances at Ep = 3.249 and 3.253 MeV in 64Zn(p,γ) are identified as fragments of the d5/2 isobaric analogue resonance from (p,p′γ) angular distributions. Gamma decay schemes and angular distributions are measured. In 65Ga, the level at 2.21 MeV is assigned a spin of Jπ = 5/2−. From angular distributions and symmetry potential considerations, the level at 2.82 MeV is considered to be the antianalogue state. The analogue–antianalogue transition strength is found to be compatible with single nucleon transfer data, thus showing that the interference effects from core polarized components arc negligible in this case.

A form for the isospin coupling potential is derived using a particle–hole model and a coupled-channel treatment of the isobaric analogue resonance. It is well suited for numerical investigations. Comparison with the phenomenological approach shows that the present treatment provides interesting insights into the real and imaginary components of this potential.
