The improvement in experimental techniques for "atom-at-a-time" studies of elements with both short half-lives and small production rates has made the last decade especially fruitful in furnishing new results for elements through 108 and preliminary reports of element 112 chemistry. The new wave ...
α decay half-lives are calculated using the Q_α values obtained by Semi-empirical Shell Model in the framework of the Unified Fission Model (UFM) with the Coulomb repulsion,nuclear attraction due to proximity potential, and rotational energy due to angular momentum transfer of α particle.In ...

Germany. The radioactive decay of evaporation residues and their α-decay products was studied using a detection setup that allows measurement of decays of single atomic nuclei with very short half-lives. Two decay chains comprising seven α-decays and a spontaneous fission each were identified and...
A thin 248Cm target was irradiated with 48Ca ions at an average energy in the target of 255 MeV. Direct counting of thin recoil foils for short-lived spontaneous fission activity was done. Two long irradiations were also made and radiochemical group separations for the superheavy elements ...

Predictions for alpha-decay half-lives of heavy and superheavy elements with a generalized liquid drop model Theoretical estimates for the lifetimes of several isotopes of heavy and superheavy elements with Z = 100-126 are performed in the framework of the generalized liquid drop model including ...

This is true for all elements, except for Technitium and Promethium, which don’t have stable isotopes that could last long enough for us to find here. All the elements after uranium are man-made and radioactive with short half-lives. ...
All of these artificial elements have extremely short half-lives and often don’t exists more than a tiny fraction of a second. It isn’t known if there are stable elements further out, or if there might be stable versions of the atoms they’ve created. ...
