N2 - We measure the suppression of Penning ionization in an ultracold He(2 S-3(1)) atomic cloud after spin-polarizing the atoms by optical pumping in a small magnetic field. An upper limit of 6x10(-12) cm(3)/s for the ionization rate constant is deduced, at least a factor 20 lower than measured in an unpolarized gas.
