Upper limits for the existence of long-lived isotopes of roentgenium in natural gold

ATOMIC MASSES 261,265,289,290,291,292,293,294,295,296Rg; measured abundance in natural gold using accelerator mass spectrometry (AMS). No events observed for 261Rg and 265Rg, not confirming a positive identification in another recent study. No events observed for 289,290,292,293,295,296Rg. Two and nine events recorded apparently for 291Rg and 294Rg, respectively could be explained otherwise, thus making positive identification for Rg unlikely. Upper limits established in the range of 1016.
