摘要：

We have obtained evidence of gamma-ray emmission above 1 TeV from PSR 1706-44, using a ground-based telescope of the atmospheric Cerenkov imaging type located near Woomera, South Australia. This object, a gamma-ray source discovered by the COS B satellite (2CG 342-02), was identified with the radio pulsar through the discovery of a 102 ms pulsed signal with the EGRET instrument of the Compton Gamma-Ray Observatory. The flux of the present observation above a threshold of 1 TeV is approximately 1 x 10(-11) photons cm-2 s-1, which is two orders of magnitude smaller than the extrapolation from GeV energies. The analysis is not restricted to a search for emission modulated with the 102 ms period, and the reported flux is for all gamma-rays from PSR 1706-44, pulsed and unpulsed. The energy output in the TeV region corresponds to about 10(-3) of the spin-down energy-loss rate of the neutron star.
