F19(d, p)F20and the Nuclear Structure ofF20

The reaction ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}(d, p){}_{}{}^{20}{}_{}{}^{}\mathrm{F}$ has been studied with 16-MeV deuterons. Outgoing protons were detected in photographic emulsions in a magnetic spectrograph. Spectroscopic factors were extracted and combined with previous information and compared with results of shell-model calculations performed in a complete $\mathrm{sd}$-shell basis. Of the previously known 25 states below $E_x=4.5\mathrm{}$ MeV, angular distributions measured at 14 angles were obtained for all but the 5 at $E_x=1.824, 2.871, 3.761, 4.20, \mathrm{and} 4.21$ MeV. Strong stripping angular distributions were observed for 10 states-6 dominated by $l=2, \mathrm{and} 4$ by $l=0\mathrm{}$. These 10 states agree reasonably well in position and strength with the 10 lowest shell-model states predicted to have appreciable amounts of the configuration [${}_{}{}^{19}{}_{}{}^{}\mathrm{F}(\mathrm{g}.\mathrm{s}.\mathrm{})\otimes 1d_{\frac{5}{2}} or 2s_{\frac{1}{2}}$ neutron)].
