TL;DR: In this article, the authors investigated the effect of sub-barrier fusion on the production of fermium evaporation residues in increasingly symmetric systems and found that the experimental fusion barriers exceed the fusion barriers predicted by the proximity formalism.

TL;DR: In this article, the authors presented the charge distributions at fixed mass asymmetry and their widths seem to be due to classical statistical fluctuations, such as quantal fluctuations of the giant E1 mode.

TL;DR: In this article, the γ-rays following β−-decay of243Np and244Np were observed following chemical isolation of neptunium isotopes from the products of the reaction of 835 MeV136Xe with244Pu.

TL;DR: In this article, a search with radiochemical methods for long-lived superheavy elements in 238U targets bombarded with intense beams of136Xe ions produced negative results, and a formation cross section of ≤ 1×10−35 cm2 was deduced at 95% confidence level for nuclides with half-lives between 1 and 200 d.

TL;DR: In this paper, the upper and lower cross sections of some Cm and Cf isotopes and of Am fission isomers were determined, within the half-life range from 1 ms to 1 year.
