Neutron blocking in alpha-transfer

Miniature Neutron-Alpha Activation Spectrometer

We are developing a miniature neutron-alpha activation spectrometer for in-situ analysis of chem-bio samples, including rocks, fines, ices, and drill cores, suitable for a lander or Rover platform for Mars or outer-planet missions. In the neutron-activation mode, penetrating analysis will be performed of the whole sample using a y spectrometer and in the ex-activation mode, the sample surface w...

Neutron Transfer to the Continuum Reactions

In this contribution we show that the theory of neutron transfer to the continuum reactions is an useful tool to study different characteristics of the single particle structure of nuclei. In one example we discuss properties of the single particle resonances in Pb. Another interesting application deals with the neutron breakup from weakly bound nuclei. Here one can use the theoretical calculat...

Design and calibration of a passive detector for separating neutron, proton and alpha particles in mixed radiation fields

In this study, calibration process was carried out for deigned new CR-39 nuclear track detector for protons, neutrons and alpha particles separately under the same etching condition. In order to aim this purpose, americium-beryllium standard source (241Am-Be) and Plexiglas phantom for neutron irradiation, brass collimators and americium standard source (241Am) for alpha irradiation and the acce...
