Characteristics of a source of thermal neutrons based on an evacuated NG-400 neutron generator with the maximum flux (Φf) 2 × 1011 neutron/s for 14 MeV neutrons and 2 × 109 neutrons/s for 3 meV neutrons have been investigated. The possibilities of

Information on the biokinetics of cerium can be obtained directly from humans by using stable isotopes as tracers. Neutron, photon and proton activation analysis have all been tested as analytical techniques able to quantify different isotopes of the

The biokinetics of radioactive substances can be studied using stable tracers. For the highly radiotoxic actinides, for which no stable isotopes are available as tracers, the use of stable isotopes of lanthanides as chemically related surrogates has

Using extracted electron beam from the 30 MeV microtron of IPP a thermal neutron source was built for activation analysis. Combined (Ta−Pb)-target is used as a gamma-neutron converter, and high-pressure polyethylene is used as a moderator. For the

A significant change in the temperature behavior of the electric resistanceR(T) was detected in Tl2Ba2CuO6+δ samples after passing an electric current for a long time. The observed change can be explained mainly by the long-range electromigration of

A factorization is proposed in this article of a two-particle t-matrix for the problem of three bodies, the scattering phase and the half-mass amplitude being described exactly for any approximation order. The uniform convergence of the approximation
