Abstract

It is shown that longitudinally polarized protons can be used to induce chirality in the final states of the (p,pN)(\vec{p},pN) reaction at intermediate energies, when there exist three final-state particles with non-coplanar momentum vectors. The analyzing power AzA_z is proposed as a measure of this effect. Theoretical descriptions to obtain AzA_z based on an intuitive picture as well as a distorted wave impulse approximation are presented, showing that the helicity of incident protons is coupled to the chirality of the orbital motion of a single-particle wave function, resulting in the chirality of the final states and a large AzA_z value.
