Abstrakt:
The upgraded separator VASSILISSA was used to confirm results of previous experiments on
the synthesis of the heavy isotopes of the element 112 obtained in complete-fusion reactions of 48Ca
and 238U. An additionalreason was the non-observation of any events in the same reaction studied with
the BGS separator at Berkeley. Limits of 280 < A < 286 for the atomic mass number of the observed
spontaneously fissioning isotope were measured. The obtained results on the decay mode, half-life and
production cross-section are in agreement with those obtained in our first experiment.
