✦ Synopsis

The exact solution is presented of a fountain-like texture for 3He-A in a half-space, representing the simplest member of a class of textures discussed by Mermin which is singular on the surface only. The present texture may be regarded as the final stable configuration when a topologically unstable point singularity in the bulk of 3He-A is attracted to the surface. For this texture the orbital or anisotropy axis I distributes itself in space much like half of a dipole field, and a ring supercurrent flows near the point singularity on the surface, contributing to a total angular momentum of the order of (ps/ p )h per particle.
