An experimental study of neutron self-shielding in cobalt foils and wires has been made by an activation technique. Cobalt foils ranging in thickness from 0.0004 to 0.004 in. and 0.005 in. thick Co...

The α-particle energies of U234, U238, and Th232 have been measured with a grid ionization chamber. The electronic equipment was designed to provide low noise, high resolution, and good long term stability. Ra226, Em222, Po218, Po214, and Po210 were

In the condensation of chloral and chlorobenzene in sulphuric acid to yield DDT, the yield of DDT is increased and the rate of formation of DDT decreased by (1) decreased sulphuric acid concentration, (2) decreased molar amount of sulphuric acid, and

It has been observed that Bi208 decays mainly by K- and L-electron capture to the 2.615-Mev first-excited level of Pb208. Decay to known Pb208 levels above the 2.615-Mev level has been shown experimentally not to occur in more than 3% of the Bi208 di

The reactions Bi209(n, 3n)Bi207 and Au197(n, 3n)Au195 have been observed to occur in NRX, a thermal neutron reactor. Competing reactions leading from Bi209 or Au197 to the same products have been shown to be negligible. Within the uncertainties of th
