Abstract

The isotope Np237, produced as the decay product of the previously known 6.8-day U237, has been isolated with carrier material and some of its nuclear properties measured. The U237 was formed by means of the reaction U238(n,2n)U237. Np237 decays with the emission of alphaparticles with a half-life of about 3×106 years. It has been shown that the upper limit for the cross section for the fission of Np237 with slow neutrons is less than 1 percent of that of U235.
