Abstract

This work reports the results of 5 measurements of the 238U decay constant for spontaneous fission, λf carried out using solid state nuclear track detectors (SSNTD), resulting in a mean value of λf = (8.35±0.24)· 10−17 y−1. The neutron fluence of the irradiations needed for these measurements were monitored with thin films of natural uranium.
