Ground state capture in 14N(p,?)15O studied above the 259 keV resonance at LUNA

We report on a new measurement of 14N(p,?)15O for the ground state capture transition at Ep = 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. © 2008 IOP Publishing Ltd.
