β - delayed proton decay of proton - rich nuclei 23 Al and 31 Cl and explosive H - burning in classical novae
We have developed a technique to measure beta-delayed proton decay of proton-rich nuclei produced and separated with the MARS recoil spectrometer of Texas A&M University. The short-lived radioactive species are produced in-flight, separated, then slowed down (from about 40 MeV/u) and implanted in the middle of very thin Si detectors. The beam is pulsed and βp decay of the pure sources collected...
متن کاملBeam Halo in Proton Linac Beams
We review the present understanding of beam halo in proton linacs. Space-charge forces acting in mismatched beams have been identified as a major cause of beamhalo. We introduce a new description of the halo using the ratio of moments of the distribution of beam coordinates. We describe the beam-halo experiment that is in preparation at Los Alamos, which will address questions about the beam pr...
متن کاملProton single - particle energies in 23 F
Nucleon transfer reaction experiments on nuclei far from stability give information on the single-particle properties of these nuclei. The single-particle properties are essential for the basic test of nuclear models used for making predictions and extrapolations for the properties of nuclei even further from stability. In this paper we consider results obtained in a recent experiment by Michim...

متن کاملOne - Neutron Halo of ~ 9
We have measured the longitudinal momentum distribution of ' C, ' C, and ' C after the one-neutron breakup of ' C, ' C, and "C, respectively, using the A1200 fragment separator as an energy-loss spectrometer. The observed narrow width of 44.3 +. 5.9 MeV/c for the "C fragments indicates that ' C is a new example of a one-neutron halo, so far the heaviest ever observed. The consequences of the ob...
