31. Spin-exchange Optical Pumping of 3He with Rb/K Mixtures and Pure K
Published: 12/31/2007
Authors: Wangchun Chen, Thomas R Gentile, S E Babcock, T G Walker
Abstract: We have studied the efficiency of spin-exchange optical pumping (SEOP) in cells that contain either pure rubidium, mixtures of rubidium and potassium, or pure potassium. Optical pumping was performed with spectrally narrowed diode array lasers opera ...

Authors: Jeffrey S Nico, Maynard S Dewey, Thomas R Gentile, Hans P Mumm, Alan K Thompson, B Fisher, I Kremsky, Fred Eberhardt Wietfeldt, T E Chupp, R Cooper, E Beise, K G Kiriluk, J Byrne, Kevin J Coakley
Abstract: The theory of quantum electrodynamics predicts that beta decay of the neutron into a proton, electron, and antineutrino should be accompanied by a continuous spectrum of soft photons. While this inner bremsstrahlung branch has been previously measure ...
