Nuclear physics · born 1933
Yuri Oganessian
Oganessian has led heavy-ion research at Dubna since the 1970s and is the second person to have an element named after him during his lifetime. His strategic contribution was to identify which combinations of beam and target give a compound nucleus a realistic chance of surviving: first the cold-fusion approach using lead and bismuth targets, and then, when that route lost reach, the systematic use of the doubly magic calcium-48 beam on actinide targets.

Contribution & context
The Dubna program he directs, working with Livermore and Oak Ridge for the actinide targets, produced elements 114 through 118, extending the periodic table to the end of period 7. Element 118 was named oganesson in 2016.

Discoveries in context
The end of the seventh row ↗
Elements 104 to 118 were made a few atoms at a time, across a fifty-year competition between three laboratories, and completing the row required agreeing on what counts as proof.
