POSSIBILITY OF MEASUREMENT OF CROSS SECTION AND VECTOR ANALYZING POWERS OF p-3He SCATTERING AT THE BRONOWICE CYCLOTRON CENTER

A new possibility of continuation of few-nucleon dynamics studies at medium energies has appeared together with a new facility at the Institute of Nuclear Physics PAN in Krakow - The Bronowice Cyclotron Center (CCB). The new cyclotron PROTEUS provides a proton beam in an energy range of 70-230 MeV. Current progress in the theoretical calculations for four-nucleon (4 N) systems is a main motivation to investigate p-He-3 scattering. Due to the fact that the beam cannot be polarized, the only possibility to study spin observables is to build a polarized He-3 target system. A planned experiment assumes the construction of a cylindrical double Pyrex cell with separated pumping and target chambers with an additional polyamide film covering apertures for the passing beam and the reaction products. To polarize He-3 gas, the spin-exchange optical pumping method will be used.
