In disagreement with recent suggestions that the beta spectrum of 32P displays a non-allowed shape with a discontinous slope to the shape factor, it has been found that this transition displays the statistical shape with W0 = 1697±2 keV. Non-statistical shapes can be simulated with inadequate attention to source quality or having a small error in the end-point energy W0. It is shown that shape factor coefficients are so extremely sensitive to W0 as to make their utility doubtful. In view of existing uncertainties, a new determination of the shape factor of the highest energy first-forbidden non-unique beta transition in 124Sb confirms the “modified Bij approximation” of Kotani and shows a shape factor C(W) = q2 + λ1p2 + D with D = 7 ± 2. The end-point energy is W0 = 2301 ± 4 keV. |
