Fission in the landscape of heaviest elements: Some recent examples
Résumé
The fission process still remains a main factor that determines the
stability of the atomic nucleus of heaviest elements. Fission half-lives vary
over a wide range, 10−19−1024 s. Present experimental techniques for the
synthesis of the superheavy elements that usually measure -decay chains
are sensitive only in a limited range of half-lives, often 10−5−103 s. In
the past years, measurement techniques for very short-lived and very longlived
nuclei were significantly improved at the gas-filled recoil separator
TASCA at GSI Darmstadt. Recently, several experimental studies of fissionrelated
phenomena have successfully been performed. In this paper, results
on 254−256Rf and 266Lr are presented and corresponding factors for retarding
the fission process are discussed.
