High density noble gas detectors and search for massive neutrinos in the [beta]-decay of [superscript 35] S
This thesis is divided into two parts. In Part I, I present a series of studies of high density noble gas detectors, the goal of which was to determine the feasibility of a [superscript 136] Xe [beta][beta]-decay detector. The limitations of liquid, high pressure and solid xenon and argon detectors...
