F. Abstract Evidence for anomalous periodicity in TeV gamma-rays that is about 0.1 percent shorter than the X-ray period, has been observed from Her X-1. It is suggested that such periodicity may result from the interaction of a broad particle beam with target matter removed from the accretion disk by instabilities at the disk/magnetosphere interface. Such target matter will initially travel in a Keplerian orbit about the pulsar. Very high energy gamma-rays are observed only when the target matter is between the neutron star and the observer. As such, the gamma-rays are observed to be pulsed at the period of the Keplerian orbit.
