The application of liquid xenon in high resolution detectors for gamma ray astronomy is being investigated. Initial results from a pulse shape analysis of ionization signals in a liquid xenon gridded chamber indicate that we are able to achieve the necessary liquid purity for the transport of free electrons with simple techniques. The energy resolution has been measured as a function of applied electric field, using electrons and ..gamma..-rays from a /sup 207/Bi source. At a field of 12 kV/cm the noise subtracted energy resolution of the dominant 569 keV ..gamma..-ray line is 34 keV FWHM. This value, which is the best reported to date in liquid xenon at similar field strengths, is mostly determined by recombination of electron-ion pairs on delta-electron tracks.
