title: Determination of the absolute alpha-particle emission probabilities of 237Np
abstract: In the framework of the EUROMET project No. 416, decay scheme data of 237Np were measured by alpha-particle spectrometry. Emission probabilities of alpha-particles and gamma-rays were determined in the past at IRMM. After improvements of the detector system and the electron bending magnet the alpha-particle measurements have been repeated. As a result, the absolute emission probabilities of 20 alpha-particle transitions were obtained with a significant lower uncertainty. Among those transitions already known, five new were found.
