Abstract

We propose a degenerate perturbation theory model for mass splitting within the 70, 1^- baryon multiplet. It is found that dominance of the lowest-lying two-body 56 × 35 intermediate states produces mixing angles in fair approximation to those previously deduced from SU(6)_W analysis of decay data. We are able to predict the couplings of all hitherto undetected members of the multiplet and to make a number of mass predictions. Our results call into question the nature of Λ(1405).
