Abstract
We have examined the double-beta decay mode accompanied by Majoron emi ssion. After 223 days of measurement corresponding to about 615 kg d o r 19.3 mol yr of exposure we find a lower half-life limit for this dec ay channel of T1/2(0nuchi) > 1.66(1.99) x 10(22) yr [90% (68%) C.L.] y ielding a new limit for the Majoron-neutrino coupling of [g(nuchi)] < 1.8 x 10(-4) (90% C.L.).
