Dirac delta spherical potential

[neworder1]

Homework Statement

Three-dimensional particle is placed in a Dirac delta potential:

$$V = -aV_{0}\delta(r-a)$$

Find energy states and eigenfunctions for the angular quantum number $$l = 0$$.[/

The Attempt at a Solution

It's not clear to me what boundary conditions will do in this case - is this analogous to 1D case?
