Cross-section models of liquid para H2 and solid CH4 for design of an advanced cold-neutron source

Cold and thermal neutron scattering in liquid water—II: Scattering laws and group constants for HO and DO

“…The group-constant sets will be utilized for design and analysis of a neutron source and a nuclear reactor. By the combined use of the group constants for liquid 4 He, H 2 ; D 2 ; and CH 4 and solid CH 4 [20][21][22][23][24][25]32,33], it will be possible to proceed with the research and development of advanced pulsed and steady-state sources for ultra-cold, cold and thermal neutrons. …”

“…Some improvement for the description of coherent scattering has been made on liquid argon [31] and liquid H 2 and D 2 [20].…”

“…The former may be commonly used in a multi-group neutron transport analysis and the latter in a continuous-energy Monte Carlo calculation. By a combination with the already-generated libraries for liquid H 2 and D 2 and solid CH 4 [19][20][21][22], we may proceed to study design and analysis of an advanced cold-neutron source [23][24][25].…”
