S- and P-Wave Interactions of K- Mesons in Hydrogen
Abstract
The experimental study of low-energy K--meson interactions in a hydrogen bubble chamber is continued and the energy range extended to a region that involves P waves. Scattering and hyperon-production cross sections are measured at mean K--meson laboratory momenta of 300 Mev/c and 400 Mev/c. Elasticscattering angular distributions are obtained and, along with the values of the cross sections, indicate the presence of P waves. Based on 289 observed decays, the measured K--meson mean lifetime is (1.31+/-0.08)×10-8 sec.
