Ground state capture in ${}^{14}$N(p,$\gamma$)${}^{15}$O studied above the 259 keV resonance at LUNA

Abstract

We report on a new measurement of ${}^{14}$N(p,$\gamma$)${}^{15}$O for the ground state capture transition at $E_p$ = 360, 380 and 400 keV, using the 400 kV LUNA accelerator. The true coincidence summing effect --the major source of error in the ground state capture determination-- has been significantly reduced by using a Clover--type gamma detector.
