When Meitner's young physicist nephew Otto Robert Frisch came to visit her in Sweden over Christmas, they realized that barium could have been formed only if absorption of a neutron had induced the uranium nucleus to split in half, and they predicted the large amount of energy that would have been released in the process.

Shortly after, their Austrian co-worker Lise Meitner (a political refugee in Sweden at the time) and her nephew Otto Robert Frisch correctly interpreted the results as the splitting of the uranium nucleus after the absorption of a neutron — nuclear fission — which released a large amount of energy and additional neutrons.
