Effect of roton backflow on quantum evaporation from superfluid 4He

We investigate the effect of roton backflow on the scattering of atoms, rotons, and phonons at the free surface of superfluid 4He at T=0 K by including backflow semiphenomenologically in the form of a backflow potential in the theory of Sobnack, Inkson, and Fung [M. B. Sobnack, J. C. Inkson, and J....
