   PR # 21065
      We propose an observation of a gamma-ray-emitting radio pulsar PSR1
    706-44. High energy gamma-rays were detected from this pulsar both by
    the EGRET on Compton gamma-ray observatory(CGRO) and by the telescope
    of Project CANGAROO. By observing this pulsar in X-ray region we can 
    study an emission mechanism of the spin-powered pulsars.Observed Xray
    pulse shape will be compared with known gamma-ray pulse to clarify a 
    structure of magnetosphere of the pulsar. Furthermore,observed energy
    spectra will tell us physical condition of a neutron star such as its
    surface temperature. All these information are indispensable to under
    stand the pulsar and the proposed observations of pulsars by ASCA    
    will make great contributions to the pulsar astronomy.
