Temperature dependent ultracold neutron transmission in D${}_2$ gas $-$ a test of the Young-Koppel model

G. Bison, R. Grössle, K. Kirch +4

The Young-Koppel model (YK) describes comprehensively the interaction of slow neutrons with diatomic gases such as H${}_2$ and D${}_2$. This paper reports on the first experimental res…
