The limit obtained here is significantly higher than the one quoted in previous publication : (

values).
(M.L.).
yr (145.1 days) the ratio of the number of observed inverse
-decay events to the expected number of events without disappearance is
for
energies
3.4 MeV.
The deficit of events is inconsistent with the expected rate for standard
propagation at the 99.95% confidence level.
In the context of two-flavor neutrino oscillations with CPT invariance,
these results exclude all oscillation solutions but the "Large Mixing Angle" solution to the solar neutrino problem using reactor
sources.
