The thermal component of the 8 GeV/c pi+ Au data ISiS Collaboration is shown to follow scaling predicted by Fisher's model when Coulomb energy taken into account. Critical exponents tau and sigma, critical point (p(c),rho(c),T(c)), surface coefficient c(0), enthalpy evaporation DeltaH, compressibility factor C(F)(c) are determined. For first time, experimental phase diagrams, (p,T) (T,rho), describing liquid vapor coexistence finite neutral nuclear matter have been constructed.
The x-ray cascade from antiprotonic atoms was studied for $^{208}\mathrm{Pb}$ and $^{209}\mathrm{Bi}$. Widths shifts of the levels due to strong interaction were determined. Using modern antiproton-nucleus optical potentials, neutron densities in nuclear periphery deduced. Assuming two-parameter Fermi distributions (2pF) describing proton densities, rms radii deduced both nuclei. difference $\ensuremath{\Delta}{r}_{\mathit{np}}$ equal...
It is widely recognized that economies of scale enhance the competitiveness large-scale nuclear reactors compared to small modular light-water (SMRs). As such, choosing an appropriate strategy crucial for future SMRs. Their development still in early stages, and among leading projects, two distinct approaches technical innovation can be observed. In some innovations are rejected because they perceived as triggers risky, costly, long-term processes. other viewed a means achieve substantial...

Excitation-energy-gated two-fragment correlation functions have been studied between 2 to 9A MeV of excitation energy for equilibrium-like sources formed in $\pi^-$ and p + $^{197}$Au reactions at beam momenta 8,9.2 10.2 GeV/c. Comparison the data an N-body Coulomb-trajectory code shows a decrease one order magnitude fragment emission time interval 2-5A MeV, followed by nearly constant breakup higher energy. The observed is shown be strongly correlated with increase probability, onset...
Nuclei with Z up to 82 emitted in the $^{208}\mathrm{Pb}$${+}^{197}$Au reaction at ${\mathit{E}}_{\mathrm{lab}}$=29 MeV per nucleon have been measured as a function of associated neutron multiplicity. The data reveal presence strong correlations between character collision and trends suggest disassembly nuclear system into large number nucleons small fragments events highest In such events, approximately one-third neturons are released from fragment yields decrease an exponential fashion...
The annihilation of energetic (1.2 GeV) antiprotons is exploited to deposit maximum thermal excitation (up 1000 MeV) in massive nuclei (Cu, Ho, Au, and U) while minimizing the contribution from collective such as rotation, shape distortion, compression. Excitation energy distributions $d\ensuremath{\sigma}/{\mathrm{dE}}^{*}$ are deduced eventwise observation whole nuclear evaporation chain with two $4\ensuremath{\pi}$ detectors for neutrons charged particles. produced this way found decay...
Annihilation of 1.2 GeV antiprotons has been explored as a means to generate high thermal excitation in heavy nuclei (U, Au, Ho) and observe their decay with minimal contribution from dynamical distortion. Conventional fission residue formation are found dominate the up ${E}^{*}\ensuremath{\approx}1000\mathrm{MeV}$. Both modes increasingly accompanied by modest emission intermediate-mass fragments (up 1 on average), but true multifragmentation is not observed. These features agreement...
Measurements of neutron multiplicity distributions 1.94 to 5.0 GeV/$c$ proton-, antiproton-, pion-, kaon-, and deuteron-induced spallation reactions on thin (few mm thick) thick (35--40 cm targets are presented. The 4$\ensuremath{\pi}$ detector employed for the first time measure from is described. Results compared with intra- internuclear cascade model calculations.
The formation and subsequent decay of nuclei excited via the annihilation 1.22-GeV antiprotons have been investigated at low energy antiproton ring (LEAR). Both neutrons charged products, from protons up to fission fragments heavy residues, were detected over a solid angle $4\ensuremath{\pi}$ by means Berlin neutron ball (BNB) silicon (BSiB), respectively. All events associated with an inelasticity greater than 10 MeV recorded, condition fulfilled for 100% events. distributions excitation...
The neutron-to-proton density ratio at the nuclear periphery was determined for six targets from yield of nuclei with mass ${(A}_{t}\ensuremath{-}1)$ generated by antiproton annihilation on number ${A}_{t}.$ A new setup allowed us to measure this half-lives down 6 s. experiment confirmed negative correlation between peripheral and neutron binding energy, which had been previously found. Results Hartree-Fock-Bogoliubov relativistic Hartree-Bogoliubov calculations show good agreement a large...
The relation between excitation energy and reaction observables has been examined for (6.0–14.6)−GeV/c protons, (5.0–9.2)-GeV π−, 8.0−GeV/c antiprotons incident on a 197Au target. Relative to proton π− beams, are found be the most effective projectile depositing high energies in targetlike residue. For protons excitation-energy distributions nearly identical appear independent of beam momentum above 6–8GeV/c. It is that total measured charge, thermal energy, charged-particle multiplicity...
