First beta-nu correlation measurement from the recoil-energy spectrum of Penning trapped Ar-35 ions

Popis výsledku v původním jazyce

We demonstrate a novel method to search for physics beyond the standard model by determining the beta-nu angular correlation from the recoil-ion energy distribution after beta decay of ions stored in a Penning trap. This recoil-ion energy distribution is measured with a retardation spectrometer. The unique combination of the spectrometer with a Penning trap provides a number of advantages, e.g., a high recoil-ion count rate and low sensitivity to the initial position and velocity distribution of the ions and completely different sources of systematic errors compared to other state-of-the-art experiments. Results of a first measurement with the isotope Ar-35 are presented. Although currently at limited precision, we show that a statistical precision of about 0.5% is achievable with this unique method, thereby opening up the possibility of contributing to state-of-the-art searches for exotic currents in weak interactions.
