The primary challenge in directly measuring nuclear reaction rates near stellar energies is their small cross sections. The signal-to-background ratio in these complex experiments can be significantly improved by employing high-current (mA-range) bea

Measurements of the 2H(d, n)3He transverse vector polarization-transfer coefficient $${K^{y'}_{y}}$$ at 0° are reported for 29 outgoing neutron energies between 3.94 and 8.47 MeV. Our new results determine $${K^{y'}_{y}(0^{\circ})}$$ more accurately

An atomic beam polarized ion source, used heavily since 1989 for producing polarized H± and D± beams for experiments between 25 keV and 20 MeV, have been modified to accept a Lamb–shift, spin–filter polarimeter. In this source, polarized ground

We have designed, built and implemented a compact polarimeter for spin-polarized proton and deuteron beams based on the Lamb-shift principle. We briefly describe some design considerations and present first results obtained with this polarimeter. (C)

A newly constructed source of polarized H ± and D ± ions is described. Atomic H or D beams from a dissociator with a cooled nozzle enter a system of two sextupole magnets and several radio-frequency transitions where they are focused and polarized.
