Targets consisting of 3,4He implanted into thin aluminum foils (approximately 100, 200 or 600 ug/cm^2) were prepared using intense (a few uA) helium beams at low energy (approximately 20, 40 or 100 keV). Uniformity of the implantation was achieved by a beam raster across a 12 mm diameter tantalum collimator at the rates of 0.1 Hz in the vertical direction and 1 Hz in the horizontal direction. Helium implantation into the very thin (approximately 80-100 ug/cm^2) aluminum foils failed to produce…

New measurement of the proton capture rate on 7 Be and the S 17 ( 0 ) factor

The 7Be(p,gamma)8B reaction plays a central role in the evaluation of solar neutrino fluxes. We report on a new precision measurement of the cross section of this reaction, following our previous

The3He(α,γ)7Be reaction and the solar neutrino problem

The capture reaction3He(α,γ)7Be has been investigated in the energy range ofEc.m. =107 to 1,266 keV. The4He or3He beams of up to 300 μA particle current were incident on3He or4He gas targets,

Lifetimes of the Ne-21 2796-, 1747-, and 2867-keV levels

The mean lives of the /sup 21/Ne 1/2/sup +/, 7/2/sup +/, and 9/2/sup +/ levels at 2796, 1747, and 2867 keV have been measured using the /sup 4/He(/sup 18/O,n)/sup 21/Ne reaction near threshold and
