摘要：

The bright gamma-ray source Geminga has been identified as an x-ray and gamma-ray pulsar with a pulse period of 237 ms. Geminga was observed with the University of Durham very high-energy (VHE) gamma-ray telescopes at Dugway, Utah, in 1983. The analysis of these data has revealed pulsations at the x-ray/gamma-ray pulse period, with the VHE gamma-ray pulses being in phase with the lower-energy gamma-ray pulses. The VHF and HE gamma-ray light curves are connected with a significance for positive correlation of 6 x 10(-4). The VHE gamma-ray signal corresponds to a flux of about 3 x 10(-11) cm-2 s-1 at energies greater than 1000 GeV, and a luminosity of 6 x 10(30) erg s-1.
