Some two body final states of K- p interactions at 1.328 GeV/c
… the Lawrence Radiation Laboratory's 72-inch hydrogen bubble chamber and the Scanning- Measuring Projector (SMP). We determined the total and partial cross sections and where possible the production and polarization angular distributions. of the final states. The angular distributions are …

Part one: The reaction K-d -> K°nm, from threshold to 300 Mev/c; Part two: K+p elastic scattering: 80-280 Mev/c
… has been performed using the Berkeley 15 inch Hydrogen bubble chamber to measure the low energy K+ p elastic scattering cross section. Although the differential cross section is generally lower than those obtained by StUbbS,,!! the experiments are consistent to within the quoted experimental …

The reaction K[superscript -] + p [right arrow] K[superscript -] + p + [pi][superscript +] + [pi][superscript -] at 2.63 and 2.70 BeV/c
… has been performed using the 72"" Alvarez hydrogen bubble chamber with incident K- beams of 2063 and 2070 BeV/c. In a film sample of 90,000 frames, 9307 4-prong, zero V events were found and measured on SMP~s. The events were fitted using the Berkeley analysis program~ PACKAGE, and 1857 …

The pi-minus proton omega channel in pi-minus proton interactions at five BeV
… study were obtained with the Alvarez 72-inch hydrogen bubble chamber. *0 N production and B production were both observed. From a moment analysis of the angular distributions in the sequential decays B -> wpi, w -> 3pi, the B is found to have either JP = 1+ or JP = 2+3-4+ A qualitative …

The reaction p p -> p p pi+ pi- at 7.9 BeV/c
… of 7.9 BeV/c using the Brookhaven 80 inch hydrogen bubble chamber. App'roximate1y 3600 events of the 'reaction were identified; the cross section was determined to be 2.54 +/- .13 mb. The reaction is found to be dominated by production of the quasi-three body final state N*++ p pi-. A …

The reactions K-p -> Sigma±pi±, Sigma±pi±pi+pi-, and Sigma±pi±K+K- at 4.1 GeV/c and 5.5 GeV/c
… 4.1 GeV/c and 5.5 GeV/c in the MURA thirty-inch hydrogen bubble chamber. K track lengths equivalent to 0.95 IJ.b per event and 0.27 IJb per event have been analyzed at 4.1 GeV/c and 5.5 GeV/c, respectively. Differential cross sections are given for the ~rr+ final states, and the results obtained …

Photoproduction of positive pions near threshold in hydrogen
… very near threshold 0 To do this, a 1410 hydrogen bubble chamber was used in an X-ray beam with Emax = 230 MeV. Meson tracks could be observed from their origins in the photon beam. Only those events were used in which the '1T+ stopped and decayed in the visible region of the chamber. To …

A study of the K[superscript -] + p [right arrow] K + N + [pi] reactions at 1.33 BeV/c
… interactions using the 72"" Alvarez liquid hydrogen bubble chamber. As part of that experiment the University ·of Illinois group investigated the following topologies: 2-prong, 2-prong with 1 kink, and O-prong with an associated vee. In particular, the reactions K + P -+ R + N + rr are …

Strange-particle production in 8 BeV/c proton-proton interactions
… pictures were obtained of the 80 Ii Brookhaven hydrogen bubble chamber exposed to 8 BeV/c protons. All 2, 4, 6, and 8 prong events with one or more associated kinks or V's were scanned for and 7,300 candidates for strange particle events were found. Of these, 3,600 were successfully measured …

A-2 meson production in pi-minus proton interactions at five BeV
… at 5 BeV/c in the 72""Alvarez liquid hydrogen bubble chamber. The p pi decay mode in the 4-constraint, p pi+ pi- pi- final state is treated in detail. Fit.s to the 3TI invariant mass spectrum yield a central mass value and width of 1.296±.008 and .l05±.035 BeV. respectively, for the A2 …
