The experiment was performed at the Solotvina Underground Laboratory w
ith CdWO4 crystal scintillators enriched in Cd-116 to 83%. For the tot
al data collection time about 12000 hours the limit of half-hfe T-1/2(
0v) greater than or equal to 3.2 . 10(22) y (90% CL) was obtained for
0v beta beta decay of Cd-116 which corresponds to the restriction of t
he neutrino mass less than 3.9 eV.
