The L/K ratios for the Xe127 electron capture decay to the 377 keV and 204 keV excited states of I127 were measured by the X-γ coincidence method. The disintegration energy and the log ƒt values were calculated. The results are disintegration energ

The neutron capture resonance integrals of Mn55, In115, Sb121, Sb123 and La139 have been measured by activation techniques taking the neutron capture reaction on Au197 as the reference. The following values have been measured for the resonance integr

Summary 18F has been produced irradiating LiN03 in the Ispra 1 reactor, by 16O(t, n)18F reaction using tritons from 6Li(n, t)4He reaction. A simple method is proposed for the purification of 18F, based on the adsorption on anionic alumina in OH- form

The number of K X-rays emitted per disintegration of 103mRh has been measured by evaluating the XK emission with a 6 mm thick NaI(Tl) crystal, and by evaluating the absolute 103mRh activity by means of a 4πβ-γ measurement of 103Ru samples in which

The half-lives of Au195, Pt195m, and Pt197 have been measured. The radionuclides were produced by neutron irradiation in the NRX reactor at Chalk River and were radiochemically purified after the irradiation. The decay of the X rays and γ-radiations

The fission yields of nine nuclides (eight belonging to the heavy mass region) for the fast fission of 232 Th by pile neutrons have been determined using radiochemical techniques. In preliminary experiments the fission yields of six nuclides for the
