Experiments Concerning the Low-Energy States of theO19Nucleus

Abstract

Angular distributions have been measured for three groups of protons from the ${\mathrm{O}}^{18}(d, p){\mathrm{O}}^{19}$ reaction, those leaving ${\mathrm{O}}^{19}$ in its states at 0, 0.096, and 1.47 Mev. Deuteron energies of 1.74 and 2.50 Mev in the laboratory system were used. The distributions of protons leaving ${\mathrm{O}}^{19}$ in its ground state and in its 1.47-Mev state are characteristic of stripping and indicate the formation of the ground state by an $l=2\mathrm{}$ neutron and of the 1.47-Mev state by an $l=0\mathrm{}$ neutron. However, the distribution of protons leaving ${\mathrm{O}}^{19}$ in its 0.096-Mev state does not lend itself to a stripping interpretation.
