The relative photodetachment cross section for decay into the H({ital N}=2) channel by the {sup 1}{ital P}{degree} shape resonance in H{sup {minus}} was measured, as well as that for decay into all channels. The branching ratio {sigma}({ital N}=2)/{s

A systematic experimental study of inclusive pion double charge exchange in {sup 4}He has been undertaken. The reaction {sup 4}He({pi}{sup +},{pi}{sup -})4p was observed at incident energies of 120, 150, 180, 240, and 270 MeV; the {sup 4}He({pi}{sup

We report a measurement of parity nonconservation in the transmission of 800-MeV longitudinally polarized protons through an unpolarized, 1-m liquid-hydrogen target. The dependence of transmission on beam properties was studied to measure and to corr

The two major proposed first-order test theories for special relativity are shown to be equivalent. The results of many experimental tests of special relativity are given in terms of the free parameters of this unified test theory.
