Polarization in Stripping Reactions

Final-state interaction and recoil polarization in reactions: comparison with the polarized target case

“…The first mechanism is similar to the one found in quasielastic proton scattering (News polarization [22,23], Maris effect [24]). In these reactions the dominance of one side of the nucleus (with respect to the final momentum of the nucleon, p ′ ) emphasizes a definite orientation of the initial orbit, and then also favors a definite orientation of the nucleon spin.…”

“…There are two dominant sources of induced polarization: the imaginary central (W C ) and real spin-orbit (V LS ) potentials. The most familiar source of induced polarization is produced by W C and arises from the correlation between absorption and initial spin that is commonly known as the Newns polarization [22,23] or the Maris effect [24]. However, spin-orbit distortion is the largest source of induced polarization for the present reaction.…”

Nucleon Knockout by Intermediate Energy Electrons

“…The EEI optical potential is used, electron distortion is treated in EMA, and the NR4 current is used. In the In hadronic reactions, such as (p, 2p), the induced polarization due to the correlation between absorption and spin is known as the Newns polarization (234,235) or Maris effect. (236) The same effect is also present in (or any reaction involving an outgoing nucleon).…”
