Transmutation of Nitrogen by Protons from 100 kev to 135 kev

A portion of the excitation curve of the thermonuclear reaction ${\mathrm{N}}^{14}(p, \ensuremath{\gamma}){\mathrm{O}}^{15}$ has been measured using protons of 100 to 135 kev. The cross section of this reaction ranges from (8.5\ifmmode\pm\else\textpm\fi{}3.7)\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}12}$ barn at 100 kev to (1.4\ifmmode\pm\else\textpm\fi{}0.3)\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}10}$ barn at 135 kev. The approximate constant ${S}_{0}$ is defined by ${S}_{0}=E\ensuremath{\sigma}\mathrm{exp}(31.281{Z}_{p}{Z}_{n}{A}^{\frac{1}{2}}{E}^{\ensuremath{-}\frac{1}{2}})$, where $E$ is the energy in the center-of-mass system and is measured in kev, $\ensuremath{\sigma}$ is in barns, $A$ is the reduced mass of the interacting nuclei, and ${Z}_{p}$ and ${Z}_{n}$ are the nuclear number of protons and nitrogen, respectively. Based upon these measurements, ${S}_{0}=2.7\ifmmode\pm\else\textpm\fi{}0.2$ kev-barn.
