Study of the 86Sr(ρ, α)85Sr reaction

Abstract

The structure of the 85Sr nucleus has been investigated by measuring the angular distributions of α-particles from the 86Sr(ρ, α)85Sr reaction at a bombarding energy of 17.5 MeV, with a 90 cm split-pole magnetic spectrograph. Angular distributions from 6° to 80° have been obtained for the ground state and levels with excitation energies of 0.23, 0,74, 0.90, 1.14, 1.23, 1.62, 1.96 and 2.14 MeV. A DWBA analysis provides l-values and spectroscopic factors for all but one of these levels.
