THE cross-section for capture of thermal neutrons in helium according to the reaction has been measured relative to the similar reaction in nitrogen for which the cross-section is given as 1路7 barns1 : Cloud-chamber photographs of the helium reaction by slow neutrons have recently been ...
FERMI and his collaboratorshave reported that neutrons slowed down by collisions in substances containing hydrogen are captured by many nuclei very much more frequently than are fast neutrons. In the cases reported, the process is one of pure capture, resulting in the formation of a higher isotope...
In order to inquire further into the circumstances responsible for the cases of agreement, the cross section for direct neutron capture with the emission of an electric dipole 纬-ray is evaluated with the help of the optical model. Comparison with experiment shows that one of the six cases of...
