Low multipolarity magnetic transitions inS32excited by electron scattering

Electron scattering cross section measurements on ${}_{}{}^{32}{}_{}{}^{}\mathrm{S}$ have been made at incident electron energies between 34 and 74 MeV and at scattering angles of 162.4° and 180°. Form factors were deduced for transitions to states at 8.11, 9.68, 10.05, 10.78, 11.12, and 11.63 MeV. Additional peaks at 7.12, 12.02, and 13.36 MeV were observed in some spectra. Comparisons of cross sections at different angles show that the above six transitions are transverse. Comparison of the experimental form factors with those calculated using an oscillator shell model indicate that the 8.11, 9.68, 11.12, and 11.63 MeV transitions are $M1\mathrm{}$. Transition probabilities $B\left(M1\mathrm{}\right)\mathrm{}\uparrow =1.14\mathrm{}\pm 0.18$, $0.69\pm 0.20$, $2.40\pm 0.22$, and $1.26\pm 0.20 {\mu }_0^2$, respectively, were determined for these four transitions. The $M1\mathrm{}$ form factors and transition probabilities are also compared with other theoretical shell model calculations. The transition at 10.78 MeV is probably $M2\mathrm{}$, or a mixture of $M2\mathrm{}$ and transverse $E2\mathrm{}$ transitions to unresolved states at about that energy.
