Fz. Huang et al., TRANSMISSION OF SLOW-NEUTRONS (8-15-ANGSTROM) THROUGH SUPERFLUID LIQUID-HELIUM, Journal of low temperature physics, 107(3-4), 1997, pp. 305-315
Transmission of very slow neutrons through superfluid liquid helium ha
s been measured from 8 to 15 Angstrom neutrons at temperatures between
0.45 K and 2.4 K. The results are compared with the single phonon emi
ssion and absorption theory.
