280Rg
NUBASE2020 said that 280Rg (T1/2 = 4.3(5) s) is 100% α. Indeed, the energy difference between 280Rg and 280Ds is (280.16514 - 280.16131)×931.4941 = 3.5676 MeV, which is much much higher than the 1.022 MeV threshold of positron emission, so EC seems strange here. 129.104.241.162 (talk) 01:31, 13 February 2024 (UTC)
 * There has been some unclarity regarding what exactly is happening in the decay chains of moscovium isotopes, because the detectors used in the experiments could not detect EC. I suspect that weak decay modes exist for some of the intermediate steps (and indeed it's quite plausibly positron emission instead of EC), but that they are small enough branches that current statistics do not allow us to pin them down. Hopefully, the SHE factory will change this, but current results still are not enough. Double sharp (talk) 15:12, 6 April 2024 (UTC)
