Abstrakt: A possible right-handed component affecting electron-neutrino helicity is probed using a Compton polarimeter. Compared to previous experiments of this kind, the systematic uncertainty is significantly reduced by independently calibrating the polarimeter efficiency. The electron-neutrino helicity is measured as in agreement with previous measurements. The bigger than expected total error on H largely arises from the relatively low efficiency of the polarimeter. In connection with this, one should reanalyze the results of previous experiments. [ABSTRACT FROM AUTHOR]
