DOIAbstract
International audienceThe fission process still remains a main factor that determines thestability of the atomic nucleus of heaviest elements. Fission half-lives varyover a wide range, 10−19−1024 s. Present experimental techniques for thesynthesis of the superheavy elements that usually measure -decay chainsare sensitive only in a limited range of half-lives, often 10−5−103 s. Inthe past years, measurement techniques for very short-lived and very longlivednuclei were significantly improved at the gas-filled recoil separatorTASCA at GSI Darmstadt. Recently, several experimental studies of fissionrelatedphenomena have successfully been performed. In this paper, resultson 254−256Rf and 266Lr are presented and corresponding factors for retardin...
