✦ Synopsis
In a nearly solid quantum liquid, a longitudinal phonon can get self-trapped in a solid-like region and form a solidon, analogous to a roton with a large solid-like core. Half a solidon can be bound to a solid-liquid interface. A bound state energy of about 5 K is estimated in liquid 4He. Surface solidons are also envisaged in two-dimensional liquid layers. The experimental data on helium films are discussed.
