High-Resolution Electron and Gamma-Ray Studies and Conversion-Coefficient Measurements in Xe132

The $\ensuremath{\gamma}$-ray spectrum from the decay of $^{132}\mathrm{I}$ was measured with small- and large-volume, high-resolution Ge(Li) detectors, and 116 transitions were assigned in its decay. Selected regions of the conversion-electron spectrum were measured with an iron double-focusing spectrometer. The $K$-conversion coefficient of the 772-keV transition that was measured relative to the $K$-conversion coefficient of the 662-keV transition in $^{137}\mathrm{Ba}$ was used to normalize the electron and $\ensuremath{\gamma}$ spectra to obtain the $K$-conversion coefficients of the 262.7-, 284.7-, 505.9-, 522.6-, 621.0-, 630.2-, 650.6-, 669.8-, 671.5-, 727.1-, 809.8-, 812.3-, 954.6-, 1136.0-, 1143.4-, 1173.2-, 1372.1-, and 1398.6-keV transitions. Conversion coefficients of additional transitions were obtained from electron intensities of other work. From these conversion coefficients, each of the above transitions was assigned an $M1$ and/or $E2$ multipolarity.
