We report a theoretical study of roton-roton scattering at large tQtal momentum. We show that the hybridization of the two-roton states with the single particle excitation can give rise to a strong energy dependence of the cross section as observed by Forbes and Wyatt in direct collisions between ballistic roton beams. .doi:10.1143/ptp.85.169 fatcat:scywzsu5ove6vlfduayz2qpaku
