ResumoThe nuclear structure of the N=21 isotones $^{35}\mathrm{Si}$ and $^{36}\mathrm{P}$ and the N=20 isotones $^{35}\mathrm{P}$ and $^{36}\mathrm{S}$ is considered in the spherical nuclear shell model with the SDPF interaction. Beta and gamma decay as well as energy spectra are calculated. Results are compared to recent data on $^{36}\mathrm{P}$(${\ensuremath{\beta}}^{\mathrm{\ensuremath{-}}}$${)}^{36}$S and $^{35}\mathrm{Si}$(${\ensuremath{\beta}}^{\mathrm{\ensuremath{-}}}$${)}^{35}$P. Unique and nonunique first-forbidden beta decay are considered as well as allowed (Gamow-Teller) decay. The predictions give a good description of the observed features of the four nuclei; in particular, the predicted beta decay rates are in agreement with experiment.
