SPIN OBSERVABLE IN ANTIPROTON-NUCLEUS ELASTIC SCATTERINGS

  • Elastic antiproton-nucleus scattering is analysed by a phenomenological optical model potential with spin orbit interaction.The elastic scattering differential cross section dσ/dΩ,polarization P(θ) and spin rotation function Q(θ) can be discribed by this potential.From the comparison with 12C nucleus experiment data of differential cross section and polarization,we obtain a more realistic antiproton optical potential.

Abstract: Elastic antiproton-nucleus scattering is analysed by a phenomenological optical model potential with spin orbit interaction.The elastic scattering differential cross section dσ/dΩ,polarization P(θ) and spin rotation function Q(θ) can be discribed by this potential.From the comparison with 12C nucleus experiment data of differential cross section and polarization,we obtain a more realistic antiproton optical potential.
