A proposed neutron-neutron scattering experiment in which the neutron source would be colliding beams from an underground nuclear explosion was investigated. In particular, the accuracy to be expected was determined so as to allow evaluation of the worth of the experiment. Phase shift analysis was performed for Gaussian, Exponential, Yukawa, and Square Well spherically symmetric potentials. The energy range considered was 20 kev to 2.6 MeV. Scattering length was found to be determined to within 6% and effective range within k0% for a 10% scattering cross section accuracy. Potential depth would be determined to at least .5% and range to .3%.

(IEEE, 2015-07-01);It is known that solid-state scintillators can be used for detection of both gamma radiation and neutron flux. In the past, neutron detection efficiencies of such solid-state scintillators did not exceed 5-7%. At the same ...
