  Title: THE 63 MS PULSAR PSR J1105-6107                                                 


Abstract:
 X-ray emission holds crucial clues to rotationally-powered pulsars' energetics and
 interaction with their surroundings, yet the paucity of known sources and the
 surprising inhomogeneity of their properties has left models poorly constrained.
 Only by discovering new sources will progress be made. We request ASCA time to
 observe a newly-discovered fast pulsar, PSR J1105-6107, an excellent candidate for
 detectable X-ray emission, and a possible counterpart to EGRET source 2EG
 J1103-6106. The large possible absorption toward the source makes ASCA the X-ray
 instrument of choice. This proposal is part of a coordinated multiwavelength effort,
 which includes single dish and interferometric radio observations, and CGRO/EGRET observations.
