Abstract
singles spectra of mass-separated (11.9 ± 0.1 h) samples have been measured with high-resolution Ge(Li) detectors. Conversion-electron spectra were measured at 0.1% resolution with a magnetic spectrometer and also with a cooled Si(Li) detector. An multipolarity was found for the weak 124.42-keV transition from the previously known 511.84-keV state to the level at 387.42 keV. The 511.84-keV state in is therefore designated as the spin- member of the Nilsson state. New very weak intraband transitions (101.96 keV, and 57.3 keV, predominantly ) depopulating the state at 387.42 keV support its spin assignment. Atomic electron binding energies for the , , , and shells in Pu were obtained; small revisions in best values for Pu electron binding energies are suggested. values for the electron-capture transitions → were derived.
