Experimental Determination of the Absolute Differential Cross Sections for theO16(d, p)O17,O16(d, p)O17*, andO18(d, p)O19*Reactions

Nickel oxide foil targets were bombarded with deuterons in order to study the angular distributions of protons from the ${\mathrm{O}}^{16}(d, p){\mathrm{O}}^{17}$ (ground state), ${\mathrm{O}}^{16}(d, p){\mathrm{O}}^{17*}$ (0.875-Mev level), and ${\mathrm{O}}^{18}(d, p){\mathrm{O}}^{19*}$ (1.468-Mev level) reactions. The absolute yield of the ${\mathrm{O}}^{16}(d, p){\mathrm{O}}^{17}$ ground-state reaction was measured at ${\theta }_{\mathrm{c}.\mathrm{m}.\mathrm{}}=53\mathrm{}°$ in 35-kev steps of laboratory deuteron energy from 2.3 Mev to 3.9 Mev. A resonant-type yield was obtained, with cross sections per unit solid angle at ${\theta }_{\mathrm{c}.\mathrm{m}.\mathrm{}}=53\mathrm{}°$ of 17 mb at 2.65 Mev, 33 mb at 3.01 Mev, 19 mb at 3.25 Mev and 31 mb at 3.43 Mev. Angular distributions obtained over twenty-two center-of-mass angles from 5° to 161° at these four deuteron energies showed a forward maximum at 53° falling to a minimum of 13 mb in the neighborhood of 90° and rising gradually to 16 mb in the back angles. Fluctuations of intensity at the forward maximum provided the major contribution to maxima in the total yield at 3.0 Mev and 3.4 Mev. Differential cross sections for the ${\mathrm{O}}^{16}(d, p){\mathrm{O}}^{17*}$ (0.875-Mev level) were measured at incident deuteron energies of 3.01 Mev and 3.43 Mev. The distributions obtained were of the typical stripping type with $l_n=0\mathrm{}$. With NiO targets enriched to 23 percent in ${\mathrm{O}}^{18}$, an angular distribution was obtained with 3.01-Mev deuterons for the ${\mathrm{O}}^{18}(d, p){\mathrm{O}}^{19*}$ (1.468-Mev level) reaction. The distribution was of the character of a typical $l_n=0\mathrm{}$ type stripping distribution with cross sections of 213 mb at 5°, falling to a minimum of 11 mb at 48° and rising to a secondary maximum of 27 mb at 84°. A spin and parity assignment of ½, + to the 1.469-Mev level in ${\mathrm{O}}^{19}$ was made on the basis of the observed distribution.
