  This article deals with the uniqueness and stability issues in the inverse
problem of determining the unbounded potential of the Schr\"odinger operator in
a bounded domain of dimension 3 or greater, endowed with Robin boundary
condition, from knowledge of its boundary spectral data. These data are defined
by the pairs formed by the eigenvalues and either full or partial Dirichlet
measurement of the eigenfunctions on the boundary of the domain.
