Energy Levels inN14andC14from Deuteron Bombardment ofC13

Abstract

An approximately 50-kev thick carbon target enriched to 61 percent ${\mathrm{C}}^{13}$ was bombarded by 3.89-Mev deuterons. The neutrons resulting from the ${\mathrm{C}}^{13}(d, n){\mathrm{N}}^{14}$ and ${\mathrm{C}}^{12}(d, n){\mathrm{N}}^{13}$ reactions were detected in photographic emulsions placed at angles of 0°, 20°, 45°, and 80° with respect to the incident beam. It was possible to examine the energy level scheme of ${\mathrm{N}}^{14}$ up to 8.1-Mev excitation and by means of Butler's stripping theory to assign parities to the first three excited states.
