Over the past several contract years we have been working on five physics projects: (1) toward a derivation of an intermediate range nucleon-nucleon interaction consistent with the new dramatically altered ..pi pi.. s-wave interaction and using a new method that utilizes much shorter and simpler analytic continuation through the unphysical region that lies between the ..pi..N and ..pi pi.. physical regions of the N anti N..--> pi pi.. amplitude; (2) construction of a short range phenomenological potential that, with the theoretical part mentioned above, will give a precise fit to the nucleon-nucleon data and is parameterized for easy use in nucleon calculations; (3) phase shift analyses of the world data below 400 MeV, especially the large amount of very precise data below 20 MeV and the new data near 55 MeV that have never been analyzed properly, and determining which phases are given by theory at which energies; (4) the introduction of our elastic K-matrix formulation of the Optimal Polynomial Expansion as a first step in obtaining quicker convergence of the partial wave series at LAMPF energies; and (5) the setting up of a cooperatively evaluated and verified nucleon-nucleon researchers (or anyone else) via Telenet dial-in and by means of a published compendium. Progress on these studies are described, and the publication of Nuclear Physics Preprints is discussed. (WHK)
