We have measured the multiplicities of particles emitted in collisions between π's and p's of 1.5 to 2.5 GeV/c momentum with He and Ne nuclei in a streamer chamber. The chamber gas served as the target as well as the detecting medium. Because of the low density and 4π solid angle of the detector, it was possible to detect nuclear fragments with energies less than 5 MeV, and to essentially count all the particles emitted in a collision. Event distributions as a function of track multiplicity were obtained as well as correlated event distributions. NUCLEAR REACTIONS He (proton or pion, fragments and pions), Ne (proton or pion, fragments and pions), E=1.5, 2.0, 2.5 BeV/c; streamer chamber gas used as target with fragment energies as low as 5 MeV. Measured multiplicities and correlations of produced particle types.

NUCLEAR REACTIONS OF TANTALUM WITH 3.65-A/GeV C-12 IONS AND 3.65-GeV PROTONS

The cross sections of a number of target residues formed in the reactions of 3.65 A GeV 12C ions and 3.65 GeV protons with tantalum have been measured. The measurements have been done by direct counting of irradiated targets with a Ge(Li) gamma-ray spectrometer. Charge dispersions and mass-yield distributions were deduced from these data. The results are discussed in terms of the basic concepts of high-energy nuclear physics. They are also compared with intranuclear cascade and abrasion-ablation model calculations.

Coincidence studies performed in 4π geometry with silicon detectors and parallel plate avalanche counters have been used to measure total fission cross sections of238U,232Th,209Bi,208Pb,197Au,natYb,natHo,natTb,natSm,natTe,natAg andnatNi nuclei induced by 1 GeV protons. The experimental results agree qualitatively with cascade-evaporation calculations.
