Sr84(x,x′)andSr84(x,x′γ)Measurements with 13-MeV Protons, 12-MeV Deuterons, and 18-MeVαParticles

Inelastic scattering experiments, using the ${}_{}{}^{84}{}_{}{}^{}\mathrm{Sr}(\alpha ,{\alpha }^{\prime })$, ${}_{}{}^{84}{}_{}{}^{}\mathrm{Sr}(\alpha ,{\alpha }^{\prime }\gamma )$, ${}_{}{}^{84}{}_{}{}^{}\mathrm{Sr}(p,p^{\prime })$, and ${}_{}{}^{84}{}_{}{}^{}\mathrm{Sr}(p,p^{\prime }\gamma )$ reactions, were performed on 82.2% enriched ${}_{}{}^{84}{}_{}{}^{}\mathrm{Sr}$ targets with solid-state detectors. The 18-MeV $\alpha$-particle inelastic scattering measurements resulted in the identification of excited states at 0.793, 1.454, 1.767, 2.07, 2.447, 2.62, 2.75, 2.81, 2.87, (3.01), 3.16, 3.24, 3.32, 3.46, 3.52, 3.65, 3.96, 4.25, 4.36, 4.55, 4.66, and 4.74 MeV, whereas the 13-MeV proton measurements resulted in identification of excited states at 0.793, 1.454, (1.502), 1.767, 2.07, 2.447, 2.76, (2.81), 2.88, (3.02), 3.18, (3.24), (3.34), 3.40, (3.48), and (3.53) MeV. Angular distributions of 13-MeV deuterons inelastically scattered from the 0.793- and 2.447- MeV states were measured with an Enge magnetic spectrograph and were fitted by $L=2\mathrm{}$ and $L=3\mathrm{}$ distorted-wave Born-approximation angular-momentum-transfer curves, respectively. Deformation parameters ${\beta }_2=0.150\mathrm{}$ and ${\beta }_3=0.129\mathrm{}$ were deduced.
