Finally, on December 1 the target was changed from lead to bismuth, ready for the search for element 111. This search was made possible by deferring a positron experiment to the new year, enabling us to prolong [...] fortunate change to the beam time schedule, as it was rewarded with three decay chains of the new element 111. But that is another story. ‘Surely the most exciting of our lives.’ When we finished on December 22
