Abstract

The reaction ²⁴³Am + ⁴⁸Ca has been reinvestigated to provide new evidence for the discovery of elements 113, 115. Twenty eight new ²⁸⁸115 decay chains were detected in this reaction to increase from three to 31 the number of ²⁸⁸115 atoms observed. In addition, four new decay chains were observed for the first time and assigned to the decay of ²⁸⁹115. These new ²⁸⁹115 events have the same properties for their decay chains as those observed for ²⁸⁹115 populated in the alpha decay of ²⁹³117 produced in the ²⁴⁹Bk + ⁴⁸Ca reaction to provide cross-bombardment evidence. These new high statistics data sets and the cross-bombardment agreement provide definitive evidence for the discoveries of the new elements with Z = 113, 115, 117.
