[en] The elastic scattering for a light nuclear system ³He - α is analysed within the Generating Coordinates Method using a procedure formulated by Piza and Passos. The same numerical technique is used to describe the bond states and scattering properties. (A.C.A.S.)

[en] The absorption channel in π-³He collisions is investigated. Amplitudes are derived for the pion-induced breakup of the target into both two clusters and three free nucleons. We employ elementary absorption mechanisms of one- and two-body type, which are presently considered to be important for the description of π-nucleus collisions from the low-energy region up to the region dominated by the Δ resonance. We put the major emphasis on the few-body aspects of the process, such as the three-nucleon dynamics in the final state, and the initial-state breakup of the bound nuclear system in presence of the pion. On the other hand, we neglect pion-nucleus correlations in the initial state, which would entail a complete four-body treatment of the process. For both one- and two-body elementary absorption, the full amplitudes are explicitly represented through quasiparticle (Sturmian) expansions. The entire set of graphs corresponding to the present model is given and discussed

[en] This paper describes a proposed experiment to detect high energy photons from radiative muon capture on helium-3 using a large acceptance pair spectrometer. The target will consist of 2 liters of liquid helium-3. The negative muons from TRIUMF channel M9 will be stopped in the target. The few muons that undergo radiative capture will produce a photon spectrum which is the sum of the individual spectra from the reactions

[en] A major fraction of the physics program for Hall C involves scattering from cryogenic targets of the lightest nuclei, i.e. H, D, and ^3,4He. Argonne is constructing the He target that will consist of a 4cm cylinder, operating at a pressure of 10 atmospheres and a temperature of ∼5.2 degrees Kelvin. CEBAF is currently constructing a cryo-target system for liquid H and D cells and the cooled, pressurized helium targets. The He target system includes cell loop, the He supply systems, and the additional equipment needed to ensure minimum loss of ³He in the event of target rupture. Some of the major components have been completed, while the balance of the system will be ready for installation this fiscal year
