Abstract
Formulae are presented for the matrix elements of the various types of radiative transitions of low multipolarity that are frequently met in light nuclei. These formulae are derived on the basis on the nuclear shell-model. First of all, extreme L-S coupling and extreme j-j coupling are considered with a view to seeing if either can give an adequate account of the experimental data. It is found, in fact, that neither extreme mode of coupling can do this, but that an intermediate coupling probably could. As an example, the radiative transitions in 13N are studied in detail in intermediate coupling and are found to give considerable support to this contention.
