Abstract

The MARS group at TAMU has developed a new experimental technique to measure very low energy protons from beta-delayed proton-decay of proton-rich nuclei produced and separated with the MARS recoil spectrometer at TAMU. Recently we have investigated the beta-delayed p-decays of (23)Al [1], and (31)Cl [2], and obtained information on the resonances in the (22)Na(p,gamma)(23)mg and (30)P(p,gamma)(31)S reactions, respectively. These reactions are important in explosive H-burning in Novae [3]. Recently an experiment looking at the beta-delayed p-decay of (20)Mg was also done in order to obtain information on resonances in the (19)Ne(p,gamma)(20)Na reaction. 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 (beta-detectors) was designed. We studied different W1 and BB2 p-detectors made by MSL, and found that the thinner detectors with a small cell size are best to measure proton energies as low as 2-300 keV.
