Unexpected reduction of rf spin resonance strength for stored deuteron beams

AD Krisch, MA Leonova, VS Morozov… - Physical Review Special …, 2007 - APS
Stored beams of polarized protons, electrons, or deuterons can be spin flipped by sweeping
an rf dipole's or solenoid's frequency through an rf spin resonance. Fitting such data to the …

Unexpected enhancements and reductions of rf spin resonance strengths

MA Leonova, VS Morozov, AD Krisch… - Physical Review Special …, 2006 - APS
