F20from theC13(11B,α)20F reaction

The ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ ${(}^{11}$B,α${)}^{20}$F and ${}_{}{}^{11}{}_{}{}^{}\mathrm{B}$ ${(}^{13}$C,α${)}^{20}$F reactions have been used to populate states in ${}_{}{}^{20}{}_{}{}^{}\mathrm{F}$ up to 10.1 MeV excitation. Angular distributions and total cross sections have been extracted and compared with Hauser-Feshbach calculations. Agreement is reasonable for most states. A few states appear to be populated by an additional reaction mechanism. Candidates for high-spin states are compared with those calculated in weak coupling with (4+n)p-nh configurations. The present results are compared with results of the ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ ${(}^7$Li,p${)}^{20}$F reaction. The correlation coefficient between the two sets of angle-integrated cross sections is 0.88.
