Abstract:

The recent result from the chromium source experiment carried out by the GALLEX collaboration implies interesting limits on the parameters

\Delta m~2

and

\sin~22\theta

describing neutrino oscillations. Values of

\Delta m~2>0.17

eV

~2

for maximal mixing and of

\sin~22\theta > 0.38

for

\Delta m~2 > 1

eV

~2

are ruled out at 90\% C.L. This result improves by more than an order of magnitude previous limits on

\Delta m~2

derived from electron-neutrino oscillation experiments at accelerators.
