Spin polarization and spin alignment in hypernuclei

Abstract

Spin polarization and spin alignment of angular momenta in hypernuclei are discussed in terms of a distorted wave Born approximation. Hypernuclei produced by (${\pi }^{+}$,${\mathrm{K}}^{+}$) and (${\mathrm{K}}^{\mathrm{-}}$,${\pi }^{\mathrm{-}}$) reactions are shown to have sizable amounts of polarization and alignment. They are promising for use in spectroscopic studies of electromagnetic transitions, electromagnetic moments, and weak decays of hypernuclear states.
