“…This behaviour is due to the progressive disappearance of the pairing correlations in 246 Fm. This trend is similar to that observed in other known even-even fermium isotopes [2,25,26]. The Coriolis anti-pairing effect progressively aligning the angular momentum of high-j orbitals onto the rotation axis with increasing frequency is responsible for this upbend.…”

“…The other prominent measured transitions are regularly spaced, strongly suggesting the presence of a rotational band in 246 Fm. This observation is consistent with the systematics of even-even nuclei in this mass region and more specifically with isotopes 248 Fm and 250 Fm [2,25,26]. The following discussion is made under this hypothesis.…”

“…Deformation not only brings an increase in stability for these SHE, but also for nuclei situated in the vicinity of the nucleus 254 No (Z=102, N=152). This transfermium (Z > 100) region has been the subject of recent, extensive spectroscopic studies [2]. The combination of high-resolution silicon and germanium arrays with powerful recoil separators, for example JUROGAM and RITU, GABRIELA and VASSILISSA or GAMMASPHERE and the FMA, allows detailed spectroscopic studies to be performed [3][4][5][6][7].…”

“…The subsequent increase of sustainable counting rates allows the use of unprecedented beam intensities, which in turn necessitates the use of rotating targets. These improvements open the possibility of gathering information on the prompt deexcitation of previously inaccessible transfermium nuclei and broadens our knowledge of nuclear structure in this mass region [2].…”

“…Using the measured γ-ray energies (see table I) and assuming a rotational structure based on the ground state of 246 Fm the values of the dynamic moment of inertia ℑ (2) for the rotational band (ℑ (2) = 4h 2 /[E γ (I) − E γ (I − 2)]) and the rotational frequency (hω = E γ (I)/2) can be deduced.…”

This article gives a brief summary of the recent progress in the synthesis of new elements as well as heavy nuclei far from the stability line and in the studies of exotic nuclear decay properties including nuclear fission of heavy nuclei and chemical characterization of heavy actinides and transactinides. Experimental techniques of single‐atom detection after in‐flight separation with electromagnetic separators have made a breakthrough in discovery of new heavy isotopes. Development of automated rapid chemical separation apparatuses performing one atom‐at‐a‐time chemistry has also considerably contributed to the progress of chemical studies of the transactinides. Some key experiments exploring new frontiers of the production and chemical characterization of heavy actinides and transactinides using state‐of‐the‐art techniques are demonstrated. A short historical perspective of actinide and transactinide elements and some prospects of extending nuclear and chemical studies of heavy elements in the future are briefly presented.
