Lifetime measurements of nuclei formed in neutron emission (II). Lifetime of neptunium isotopes
Abstract
The lifetimes of the fissionable neptunium isotopes 235,236,238,239Np have been measured using the crystal-blocking technique. These isotopes were produced by deuteron bombardment of 235UO 2 and 238UO 2 single crystals with following emission of neutrons. Analysis of the experimental results was performed in the framework of the statistical model of nuclear reactions and the double-humped fission barrier model with allowance for the lifetime of the second-well states.
