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

ATOMIC MASSES ^{261,265,289,290,291,292,293,294,295,296}Rg; 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 ^{289,290,292,293,295,296}Rg. 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.
