ANALYSIS OF TWO INTERFERING 1/2+ LEVELS IN THE DISINTEGRATION OF C14 BY PROTONS

Abstract

Two interfering resonances occurring at bombarding energies of 1.32 Mev and 1.51 Mev in the reactions C¹⁴(pn)N¹⁴ and C¹⁴(pγ)N¹⁵ have been analyzed in terms of Wigner's two-level formula. Resonant energies and reduced widths have been found which give good fits to the shapes of the yield curves for both processes in the neighborhood of the resonances. The absolute cross sections for the C¹⁴(pn)N¹⁴ and N¹⁴(np)C¹⁴ reactions are obtained from the analysis without reference to the measured cross sections. The calculated cross sections are found to be about 40% lower than the measured ones.
