Abstract
The measured recently by Décamp et al. from the semileptonic decay is calculated in a constituent-quark model with harmonic-oscillator forces in even partial waves only as proposed recently by Mitra. The model provides a natural facility for an ideal mixing between the states of the and to represent the nucleon octet, with the Roper octet as the orthogonal counterpart. The theoretical prediction obtained is 0.15, to be compared with reported by Decamp et al. For the decay the corresponding is calculated as 0.778, to be compared with an experimental average value of 0.66±0.05.
