We study the influence of a contact (or delta) potential on the Aharonov-Bohm scattering of nonrelativistic particles …. In general the contact potential has no effect on the scattering as expected. However, when the magnetic flux and the … strength of the contact potential take some special values, the Aharonov-Bohm scattering cross-section is manifestly changed …
