   PR # 22096
    Our recent detection of hard, pulsed, quasi-thermal X-ray emission   
    from the hot polar cap of the nearby radio pulsar PSR1929+10 opens a 
    new window on pulsar radiation mechanisms and neutron star physics.  
    With the lowest column density and hardest spectrum of any of the de-
    tected rotation-powered pulsars,this source is an excellent candidate
    for an ASCA observation. In particular, we show how an SIS spectrum  
    will allow measurment of radiative transfer effects in the star's    
    magnetic atmosphere, constraining it's structure and chemical compo- 
    sition. A GIS light curve will allow us to locate the altitude of the
    radio emission region as well as producing a direct constraint on the
    star's radius as a consequence of measureable general relativistic   
   light bending effects.
