Identification of more than a 100 new isotopes from 238U projectile fission and beams of neutron-rich nuclei at BRENDA

Current status and future potential of nuclide discoveries

“…However, in the original publication only 50 new isotopes were listed and there was no evidence for the observation of any praseodymium or neodymium isotopes [97]. A modified version of the nuclide chart showing these nuclei was included in two further publications [98,99]. These two neodymium isotopes ( 157,158 Nd) have recently been reported (see section 5) by van Schelt et al [100] and Kurcewicz et al [101], respectively.…”

“…The remaining three nuclides, 95 Cd, 97 In and 99 Sn, bring up the discussion of what should be counted as a discovery. The particle identification plot in the recent publication by Hinke et al exhibits clear evidence for the presence of 95 Cd and 97 In and a few events of 99 Sn [163]. However, neither the text nor the figure caption mentions the discovery of these nuclides.…”

“…However, neither the text nor the figure caption mentions the discovery of these nuclides. In an earlier contribution to a conference proceeding Krücken reported the discovery of 95 Cd and 97 In, but not 99 Sn, from the same experiment [102].…”

The rare isotope accelerator project

“…At the level of 10 −5 particles/s the stability of an isotope (and hence in some cases the location of a drip line) can be determined [7,8] and its half-life measured [9,10,11] if the background is sufficiently low. At the level of 0.01 particles/s the total interaction cross section of the isotope can be determined, and information on its matter distribution can be inferred [12,13,14].…”

Complete isotopic distributions of fragments produced in transfer- and fusion-induced reactions

“…Therefore, the study of the properties of these distributions may reveal some informations about the formation and the deexcitation of the compound nucleus. The use of inverse kinematics to measure the atomic number of all the fission fragments has been developed at GSI in the 1990s [2]. Previously, the charge of the heavy fragments was rather difficult to determine.…”
