Supersymmetric elimination of forbidden states in the Coulomb breakup of the 11Be halo nucleus

Supersymmetric transformations allow eliminating forbidden bound states from a potential without affecting its scattering properties. The Coulomb breakup of the 11Be halo nucleus is studied by solving the time-dependent Schrödinger equation with phase-equivalent 10Be–neutron interactions. The differences between breakup calculations with and without forbidden states are weak but the inelastic scattering to the 1/2− state is more affected.
