Measurement Of The β-ν Correlation In ~6He Using A Transparent Paul Trap

摘要

The angular correlation between the electron and the neutrino in nuclear β-decay constitutes a sensitive observable to search for the existence of exotic couplings in the weak interaction. In this contribution, we describe the progress of the LPCTrap experiment, devoted to measure the β-ν angular correlation in the pure Gamow-Teller (GT) decay of 6He using a transparent Paul trap. We present a first coincidence spectrum, obtained during the commissioning run, which is the first β-recoil coincidence measurement obtained from any ion trap.
