The cross sections for one phonon emission and absorption by slow neutrons in superfluid liquid Helium
Numerically calculated cross sections for one phonon emission and absorption by a slow neutron in superfluid liquid helium are presented. Ultracold neutron production cross section is 22.0 mubarns after systematic corrections. Differential and total cross sections for one phonon emission and absorption by slow neutrons with no restriction in final energies are also shown. (C) 2002 Elsevier Science B.V. All rights reserved.
