High-spin (f7/2)A−40states inTi47,Sc47,Ca44,Ca45, andTi48viaC36fusion-evaporation reactions

${}_{}{}^{36}{}_{}{}^{}\mathrm{S}$ ${(}^{14}$C,xnypzαγ) reactions were used to extend our knowledge of the high-spin states of ${}_{}{}^{47}{}_{}{}^{}\mathrm{Ti}$, ${}_{}{}^{47}{}_{}{}^{}\mathrm{Sc}$, ${}_{}{}^{44}{}_{}{}^{}\mathrm{Ca}$, ${}_{}{}^{45}{}_{}{}^{}\mathrm{Ca}$, and ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ti}$. The decay schemes were constructed from γγ-coincidence data and γ-ray angular distributions and excitation functions. The angular distributions also provided information on spin-parity assignments and multipole mixing ratios. Lifetime information was extracted from analysis of the γ-ray Doppler shifts observed in both the angular distribution and γγ-coincidence data. Assuming the probable $J^{\pi }$ assignments are correct, the yrast schemes for all five nuclei extend to the highest spin allowed for ($f_{7/2}$ ${)}^{A\mathrm{-}40}$. Results are compared to shell-model predictions generated in three different configuration spaces: ($f_{7/2}$), ($d_{3/2}$,$f_{7/2}$), and the full (f,p) shell.
