The total cross section of hadron photoproduction on C, Cu and Pb nuclei is measured for six energy values in the range 12–30 GeV. The obtained cross-section values for C and Cu nuclei have a weak energy dependence at high energies (above 20 GeV). The cross section for the Pb nucleus is somewhat higher in comparison with that expected, and energy dependence is not observed. The A -dependence of the effective number of hadrons agrees with VDM predictions.

This paper contains the results of a study of the reaction K−p→Λπ0 in the center-of-mass-system-energy region of 1647 to 1715 MeV. An energy-dependent partial-wave analysis was performed in this channel. Two allowable solutions were obtained. The first solution in this region contains the D13[t=0.08±0.01, Γ(ER)=44±11 MeV, and ER=1671±3 MeV] partial wave as the only resonant amplitude; the second solution contains both the P11[t=0.16±0.01, Γ(ER)=81±10 MeV, and ER=1671±2 MeV] and the D13[t=0.17±0.01, Γ(ER)=76±5 MeV, and ER=1655±2 MeV] partial wave as resonant.

A measurement of the differential cross section for the reaction np→ π 0 d has been made at the Lawrence Radiation Laboratory 184-inch cyclotron. A neutron beam with kinetic energies up to 720 MeV was incident on a liquid hydrogen target. The angle and momentum of the deuterons were measured using an analyzing magnet and wire spark chambers with a magnetostrictive readout. Deuterons were separated from protons by time-of-flight. The photons from the decaying π 0 were not detected. The neutron energy was calculated from the measured deuteron angle and momentum.

Results are reported on K − -neutron interactions at c.m. energies near 2 GeV. The interactions are dominated by strong production of hyperon resonances, particularly Σ(1385), Λ(1405) and Λ(1520). Production cross sections and angular distributions are given for the Σ(1385), Λ(1405) and Λ(1520) and branching fractions to decay modes observed in the experiment are given for Σ(1385) and Λ(1520). The strong energy dependence of some features of the data suggests that s -channel effects are dominant.
