Lifetimes of compound nuclei generated under the 235U deuteron bombardment
Description
Life times of excited fissionable nuclei were investigated by shadow effect. The 235U(d, f) reaction was used, which was intermediate because at the deutron energy Esub(d)=(10-14) MeV the excitation energy of 237Np nucleus approximately equal to (17-21) MeV and fission after the emission of one or two neutrons is possible. 235UO2 crystal irradiation by 25.2 MeV α-particles was exercised for obtaining a standard shadow. The conducted investigations show the possibility of life time investigation relatively to long-lived nuclei foumed after decrease of excitation energy by neutron emission from the compound nucleus. The determined values of 235Np nucleus life time reveal natural tendency to decrease with the growth of excitation energy and they have reasonable value order that is proved by their comparison with data on life time of other fissionable nuclei
