Abstract

The role of beta- and gamma-ray matrix elements in the determination of wave functions for the $s^{4} p^{10}$ states of mass 14 is examined. The data considered include the Gamow-Teller (beta) matrix elements of ${}^{14}C$ and ${}^{14}O$ and the $M 1$ and $E 2$ matrix elements connecting the lowest four $s^{4} p^{10}$ states of ${}^{14}N$ . The magnetic moment of ${}^{14}N$ is also discussed. The shell-model wave functions considered arise mainly from the $s^{4} p^{10}$ configuration but include admixtures of the $s^{4} p^{8}$ ( $2 s, 1 d$ ) configuration. It is found that the data, considered as a whole, cannot be explained if the $s^{4} p^{10}$ components of the wave functions are derived from a central plus spin-orbit interaction only, but that quite satisfactory agreement is obtained if the nuclear force includes a tensor part. The bulk of the cancellation of the ${}^{14}C$ beta decay matrix element takes place within the $s^{4} p^{10}$ configuration. In general, configuration mixing is of secondary importance; its most noticeable effect is on the $M 1$ decay of the first-excited state of ${}^{14}N$ .
