Recent developments in neutrino physics

I shall attempt to summarize recent developments in the experimental situation in neutrino physics. The paper will deal with recent results, drawing on either published work or research that has been presented in preprint form, as there is an adequate supply of interesting and controversial data restricting oneself to these generally more reliable sources. The discussion of the theoretical implication of these experimental results will be presented in the following paper by Boris Kayser. The topics to be covered in this presentation are: direct measurements of bar νe mass via beta endpoint studies; status of solar neutrino observations; status of ''17-keV neutrino'' reports; and the use of νp elastic scattering to determine the ''strange quark'' content of the proton. 2 refs., 15 figs., 9 tabs
