States of Low Excitation inO18

Abstract

A new state in ${\mathrm{O}}^{18}$ at an excitation energy of 3.555±0.013 Mev is established by a proton group from the reaction ${\mathrm{O}}^{17}(d, p)$ with $Q=2.262\mathrm{}\pm 0.015$ Mev and by a deuteron group from the reaction ${\mathrm{O}}^{18}(d, d^{\prime })$ with $Q=-3.551\mathrm{}\pm 0.019$ Mev. A level reported by Ahnlund at 1.986±0.014 Mev is confirmed. No evidence is found for states between these two, in particular for one reported by Holmgren and coworkers at 2.445 Mev.
