Abstract
Abstract The angular distributions of the decay neutrons populating 1 2 − , 3 2 − and 1 2 − states of 91Nb and 95Tc resulting from the s- and d-wave proton induced Jπ = 2+ analogue resonances are investigated. The experimental angular distributions show the interference effect arising from the coherence between the partial waves involved in the resonance. The analysis of the observation shows that it is necessary and sufficient that the interference be between the s 1 2 and d 5 2 partial waves in the entrance channel. The ratios of the spectroscopic factors and the relative signs of the reduced width amplitudes for the s 1 2 and d 5 2 protons are deduced from the data. The ratios of the spectroscopic factors agree with the (d, p) results.
