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