The total cross sections and the differential cross sections of π + - 4 He elastic and inelastic reactions at E π =120, 145 and 165 MeV have been measured using a 38 cm diffusion cloud chamber in a magnetic field exposed to the Frascati Laboratories' pion beam. Total π + track lengths of (2141 ± 10) × 10 3 cm, (3435 ± 10) × 10 3 cm and (2413 ± 10) × 10 3 cm were measured at the three considered energies, respectively. The elastic cross-section data are in good agreement with the results of the Dubna-Torino collaboration. The total inelastic cross sections have been obtained taking into account the contributions from all the inelastic channels. The analysis of the various inelastic processes has allowed us to distinguish five main reaction mechanisms, which compare reasonably with the existing data and with the models for pion-light-nuclei interactions.

The direct nuclear reaction C(p,3p) at 640 MeV has been studied in an exclusive experiment. The measuring conditions were chosen in accordance with the kinematics of the two-nucleon quasifree knock-out. Phenomenological models assuming proton scattering on proton pairs are in qualitative agreement with the data.

Nucl.Phys.A

Spectra of protons of energies between 50 and 145 MeV emitted from carbon have been measured at angles from 105° to 160° with respect to the 640 MeV proton beam. The measurements have been carried out both inclusively and in coincidence with protons emitted at forward angles up to ±40° with energies from 255 MeV to 330 MeV. This energy interval has been chosen in accordance with the kinematics of quasifree scattering on two-nucleon groups. Inclusive differential cross sections at 140° and coincidence cross sections at the angle pair (− 12°, 122°) have also been measured with Be, Al, Cu and Pb targets. The data have been compared with the predictions of several models.
