X- and gamma-ray emissions observed in the decay of 237Np and 233Pa.
Solvent extraction was used to prepare pure solutions of (237)Np and (233)Pa. Portions were used for liquid scintillation counting (disintegration rates) and gamma-ray spectroscopy with HPGe detectors. X- and gamma-ray intensities observed in the (237)Np decay were verified, with a new result of 15.08+/-0.04% for the 29 keV gamma-ray (5 sigma higher than previous reports). K X- and gamma-ray intensities observed in the (233)Pa decay were verified with new results for the L X-ray intensities (approximately 55% total L intensity), approximately twice previously reported total intensity.
