Dynamics of Rotons

Part of the NATO ASI Series book series (NSSB, volume 257)


We consider the interaction of rotons with quantized vortex lines in the theory of mutual friction. A good account is given of mutual friction at low temperatures and under pressure. We also consider collisions of rotons with rotons in the context of a recent experiment by Forbes and Wyatt.
