Title: Review of Element 115 decay chains
Post by: Dan1195 on November 09, 2014, 03:13:50 PM

I know that GSI is currently reviewing some of the data obtained in the recent Element 115 and 117 experiments. Specifically, all shorter chains terminating in SF of Element 111 (Rg). With previous Dubna studies, all such reported shorter chains have been assigned to the ²⁹³117>²⁸⁹115>²⁸⁵113>²⁸¹Rg chain with SF activities assigned to ²⁸¹Rg.

The question is are all those actually ²⁹³117 or ²⁸⁹115 chains or are some them actually ²⁹⁴117 (or ²⁸⁸115 chains in the ²⁴³Am+⁴⁸Ca reaction given that the 1n reaction channel is unlikely here) ending in Electron capture (EC) decay of the odd-odd nucleus.
