摘要：

An analysis of 40 hours of data, collected at Gulmarg during 1987 and 1988, indicates absence of a significant d.c. or episodic periodic signal from 4U0115+63 (Cassiopeia gamma-1). We place an upper limit (at 99% confidence level) of 1.9x10(-11) photons cm-2 s-1 on the flux of a steady signal from this x-ray binary pulsar at primary energies greater-than-or-equal-to 3 TeV. This is consistent with the negative results reported recently by the Whipple group for the period 1985 -1988 but not with the detections claimed previously by Crimean and Durham groups.
