Query: The Rubakov-Callan Scattering on the Supergravity Monopole   We study small perturbations around the supersymmetric CVMN monopole solution
of the gauged supergravity in D=4. We find that the perturbation spectrum
contains an infinite tower of Coulomb-type bound states both in the bosonic and
fermionic parts of the supergravity multiplet. Due to supersymmetry, the
eigenvalues are the same for the two bosonic parity sectors, as well as for the
fermionic sector. We also find that the fermion scattering on the monopole is
accompanied by isospin flip. This is analogous to the Rubakov-Callan effect of
monopole catalysis of proton decay and suggests that there could be a similar
effect of catalysis for decay of fermionic systems in supergravity.
