  We study Polchinski's "fermion-rotor system" as an accurate description of
charged Weyl fermions scattering on a magnetic monopole core in the limit of
zero gauge coupling. Traditionally it was thought such scattering could lead to
fractional particle numbers ("semitons"). By direct calculations we show those
semitonic processes are in fact free propagation, facilitated by composite
fermion-rotor operators interpolating the "forbidden" states, effectively
"recovering" both ingoing and outgoing states in every lowest partial wave.
Non-semitonic Callan-Rubakov processes are unchanged.
