Abstract
The effective polarization of the residual nucleus in the proton-induced knockout reaction is investigated within the distorted wave impulse approximation framework. The strong absorption of the emitted particle results in strong selectivity on the reaction position depending on the third component of the single-particle orbital angular momentum of the particle inside a nucleus, hence on the spin direction of the reaction residue. This is caused by a mechanism that is similar to the Maris effect, the effective polarization in the proton-induced proton knockout reactions. However, as a distinct feature of the effective polarization in the knockout process, the spin degrees of freedom of the reacting particles play no role. The knockout process with complete kinematics can be a useful polarization technique for the residual nucleus, without actively controlling the spin of the proton.
