- W105681921 abstract "We have determined the ensuremath{gamma}-ray branching ratio ${mathrm{ensuremath{Gamma}}}_{ensuremath{gamma}}$/${mathrm{ensuremath{Gamma}}}_{mathrm{tot}}$ for the first excited state in $^{14}mathrm{O}$ (${mathit{E}}_{mathit{x}}$=5.17 MeV) to be (3.1ifmmodepmelsetextpmfi{}1.7)ifmmodetimeselsetexttimesfi{}${10}^{mathrm{ensuremath{-}}4}$, corresponding to a ensuremath{gamma} width of 12ifmmodepmelsetextpmfi{}7 eV. This value was determined by measuring the ratio of the $^{14}mathrm{N}$(p,n${)}^{14}$${mathrm{O}}_{0}$ to $^{14}mathrm{N}$(p,n${)}^{14}$${mathrm{O}}_{1}$ cross sections via neutron time of flight, and the ratio of $^{14}mathrm{N}$(p,n${)}^{14}$${mathrm{O}}_{0}$ to $^{14}mathrm{N}$(p,n${)}^{14}$${mathrm{O}}_{1}$(ensuremath{gamma}${)}^{14}$${mathrm{O}}_{0}$ cross sections at the same center-of-mass energy by bombarding a hydrogen target with a $^{14}mathrm{N}$ beam and kinematically distinguishing the $^{14}mathrm{O}_{0}$ recoils from the two reaction channels. The present value for ${mathrm{ensuremath{Gamma}}}_{ensuremath{gamma}}$ is consistent with other measurements at the 2-ensuremath{sigma} level; a weighted mean of all measurements is used to calculate the stellar $^{13}mathrm{N}$(p,ensuremath{gamma}${)}^{14}$O reaction rate, and thereby determine the temperatures and densities at which the stellar carbon-nitrogen-oxygen (CNO) cycle is converted to the hot CNO cycle." @default.
