Abstract
In the presence of a nonconservation measured by an angle , the ground state of a point magnetic monopole is shown to have an electric charge of value which changes discontinuously to zero for massless fermions. A new version of Levinson's theorm is also given. The latter effect as well as the -wave helicity filp of a dyon can be interpreted as a leak at the origin.
