Abstract
We study a vortex line in superfluid He-4 on the basis of a shadow wav e function. This allows for the first time the treatment of a quantum vortex in He-4 with distributed vorticity and a non vanishing density at its axis. We consider He-4 in a cylindrical bucket and by Monte Car lo method we compute the excitation energy as a function of the radial distance from the vortex axia and the density profile.
