Abstract

We have developed a new experimental technique to measure very low energy protons from β-delayed p-decay of proton-rich nuclei produced and separated with the MARS recoil spectrometer at TAMU. Recently we have investigated the β-delayed p-decays of Al[1] and Cl[2] and obtained information on the resonances in the reactions Na(p, γ)Mg and P(p,γ)S, respectively. These reactions are important in explosive H-burning in Novae [3]. A simple setup consisting of a telescope made of a thin double sided Si strip detector (p-detector) backed or sandwiched between two thick Si detectors (β-detectors) was designed. We studied two different p-detectors and found that the thinner detectors with a small cell size are best to measure proton energies as low as 2-300 keV. © 2010 American Institute of Physics.
