Abstract : The low-energy gamma-ray transitions in Np237 following alpha decay of Am241 have been studied by examination of the internal conversion spectrum at good resolution. Improved measurements of the energies and intensities of the line due to the well-known transitions of energies 26.36, 33.21, 43.44, 55.56, 59.57, and 99.00 keV have been made. The existence of a weak transition of energy 67.52 keV has been confirmed. The existence of weak transitions of energies 27, 42.8, 70, and 76 keV, previously reported, has not be substantiated.
