Excitation Functions for Nitrogen-Induced Nuclear Reactions in Carbon

Abstract

The excitation functions for the reactions ${\mathrm{C}}^{12}({\mathrm{N}}^{14}, 2p){\mathrm{Na}}^{24}$, ${\mathrm{C}}^{12}({\mathrm{N}}^{14}, \alpha ){\mathrm{Na}}^{22}$, and ${\mathrm{C}}^{12}({\mathrm{N}}^{14}, 2\alpha ){\mathrm{F}}^{18}$ were measured with the external 29-Mev nitrogen beam of the 63-inch cyclotron. Thick-target yields as a function of energy were differentiated to obtain absolute cross sections from 16 to 29 Mev. A similarity to the excitation functions for reactions produced by protons on ${\mathrm{Mg}}^{25}$ is suggested.
