“…For examp1e (18) may also be an eigenvector for IRb 86 ; 2-> , but its matrix element corresponds to the sing1e-partic1e transition v g 9 / 2 + nP3/2 and gives rise to matrix elements at least of rank 3. Consequent1y, its inf1uence to the theoretica1 expressions is extreme1y weak, and we are not ab1e to say anything about its relative contribution from beta decay analysis.…”
