“…Finally, the ISiS data demonstrate the important role that reaction dynamics exert on the statistical decay properties of hot residues. Earlier inclusive studies [42,43,44] showed the existence of sideways peaking of IMF angular distributions for p + A reactions above ∼ 10 GeV. This result was interpreted as possible evidence for dynamical IMF emission during the initial phases of the cascade, possibly signaling the existence of nuclear shock wave effects.…”

An extensive study of GeV light-ion-induced multifragmentation and its possible interpretation in terms of a nuclear liquid-gas phase transition has been performed with the Indiana Silicon Sphere (ISiS) 4π detector array. Measurements were performed with 5-15 GeV/c p, p, and π − beams incident on 197 Au and 2-5 GeV 3 He incident on nat Ag and 197 Au targets. Both the reaction dynamics and the subsequent decay of the heavy residues have been explored. The data provide evidence Preprint submitted to Elsevier Science 10 March 2018for a dramatic change in the reaction observables near an excitation energy of E*/A = 4-5 MeV per residue nucleon. In this region, fragment multiplicities and energy spectra indicate emission from an expanded/dilute source on a very short time scale (20-50 fm/c). These properties, along with caloric curve and scaling-law behavior, yield a pattern that is consistent with a nuclear liquid-gas phase transition.

“…In addition, because of the restrictions made by Katcoff and Perlman 12 to fragment energies of E ^ 5.5 MeV/nucleon and to the angular region between 0° and 45°, their value of ^fragment ^ 6 nb cannot be considered as a relevant limit for the W targets. 19,20 (The total production cross section of, for instance, 86 Sr ions is estimated to be about 1 mb. 21 ) It should also be mentioned that the above conditions cannot be fulfilled in U or Th targets.…”

Consistent Interpretation of the Secondary-Reaction Experiments in W Targets and Prospects for Production of Superheavy Elements in Ordinary Heavy-Ion Reactions

A consistent interpretation is presented of spontaneous fission events previously observed in Hg sources separated from CERN W targets. The energy spectra are interpreted in terms of fission to four fragments with ZiXtotal) -320 MeV. The value of v is estimated to be between 3 and 5. The measured masses of the fissioning nuclei are consistent with various molecules of element 112 with about 160 neutrons. The prospects of producing superheavy elements with use of targets around W and projectiles like Sr and Zr are discussed.
