Energy Levels ofFe59from theFe58(d, p)Fe59Reaction

The angular distributions of the protons from the ${\mathrm{Fe}}^{58}(d, p){\mathrm{Fe}}^{59}$ reaction leading to eight states of ${\mathrm{Fe}}^{59}$ have been measured with 10-MeV deuterons at the Argonne tandem accelerator. Data were taken from 15° to 165°. Absolute cross sections were obtained by comparing the 7-MeV deuterons elastically scattered at 20° with the ground-state protons from the ($d, p$) reaction at $E_d=10\mathrm{}$ MeV. Values of the orbital-angular-momentum transfer and spectroscopic factors were obtained by comparing the measured cross sections at the forward peaks with those calculated by means of the distorted-wave Born approximation. Spins were assigned by use of the empirical $J$-dependence rules. The assignments $E_{\mathrm{exc}}(l, J, S)$ resulting from the present work are ground state (1, $\frac{3}{2}$, 0.45); 0.287 MeV (1,½,0.22); 0.470 MeV (3, $\frac{5}{2}$, 0.54); 0.728 MeV (1, $\frac{3}{2}$, 0.20); 1.026 MeV ([3], [$\frac{7}{2}$], 0.08); 1.214 MeV (1,½,0.81); 1.572 MeV (4, $\frac{9}{2}$, 1.07); and 1.749 MeV (2, $\frac{5}{2}$, [$\frac{3}{2}$], $\frac{3.59}{\mathrm{}(2J+1)\mathrm{}}$).
