K$sup -$-p ELASTIC SCATTERING IN THE ONE Bev/c RANGE

Journal Article · · Physical Review (U.S.) Superseded in part by Phys. Rev. A, Phys. Rev. B: Solid State, Phys. Rev. C, and Phys. Rev. D
Differential K/sup -/ p elastic-scattering cross sections were measured at four momenta in the range corresponding to the T = 0, 1815-Mev K/sup -/ p resonance, using a cylindrical spark chamber sourrounding a liquid-hydrogen target. The integrated elastic-scattering cross sections follow the known resonant behavior of the total cross section, and are (18.7 plus or minus 0.7), (23.3 plus or minus 1.0), (17.3 plus or minus 1.1), and (15.2 plus or minus 0.7) mb at 820, 1040, 1150, and 1260 M(ev/c bombarding momentum, respectively. It is necessary to include cos/sup 5/ theta /sup */ terms in order to fit the angular distributions at 1040 and 1150 Mev/c, and within the accuracy of the experiment higher terms in cos theta /sup */ are not needed throughout the resonance region. This implies that the resonance is due to D/sub 5/2/ F/sub 5/2/ interference, and that the simplest assignment for the spin of the resonance is J = 5/2. No conclusion can be inferred about the parity. (auth)
