We analyze controllability properties for the one-dimensional heat equation with singular inverse-square potential u(t) - u(xx) - mu/x(2)u = 0, (x, t) is an element of (0, 1) x (0, T). For any mu < 1/4, we prove that the equation is null controllable through a boundary control f is an element of H-1(0, T) acting at the singularity point x = 0. This result is obtained employing the moment method by Fattorini and Russell.
