摘要：
This work reports the results of 5 measurements of the U-238 decay constant for spontaneous fission, lambda(f)(-), carried out using solid state nuclear track detectors (SSNTD), resulting in a mean value of lambda(f) = (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.
