Abstract
- Spectra of electrons from beta decays of 144Ce-144Pr nuclei have been measured and analyzed in order to find a contribution from a heavy neutrino. For the neutrino with the mass mνH in the interval of 150-350 keV, a new upper bound |UeH|2 ≤ (2−5) × 10−3 at 90% C.L. has been found for the mixing parameter. [ABSTRACT FROM AUTHOR]
