Nucl.Phys. A749 (2005) 65-72 Thermal multifragmentation of hot nuclei is interpreted as the nuclear
liquid-fog phase transition inside the spinodal region. The experimental data
for p(8.1GeV) + Au ...collisions are analyzed within the framework of the
statistical multifragmentation model (SMM) for the events with emission of at
least two IMFs. It is found that the partition of hot nuclei is specified after
expansion to a volume equal to Vt = (2.6+-0.3) Vo, with Vo as the volume at
normal density. However, the freeze-out volume is found to be twice as large:
Vf = (5+-1) Vo.
Phys.Rev. C70 (2004) 041601 The paper is devoted to the experimental determination of the space-time
characteristics for the target multifragmentation in p(8.1GeV) + Au collisions.
The experimental ...data on the fragment charge distribution and kinetic energy
spectra are analyzed within the framework of the statistical multifragmentation
model. It is found that the partition of hot nuclei is specified after
expansion of the target spectator to a volume equal to Vt = (2.9 +- 0.2) Vo,
with Vo as the volume at normal density. However, the freeze-out volume is
found to be Vf = (11 +- 3) Vo. At freeze-out, all the fragments are well
separated and only the Coulomb force should be taken into account. The results
are in accordance with a scenario of spinodal disintegration of hot nuclei.
Nucl.Phys. A734 (2004) 520-523 Thermal multifragmentation of hot nuclei is interpreted as the nuclear
liquid-fog phase transition. The charge distributions of the intermediate mass
fragments produced ...in p(3.6 GeV) + Au and p(8.1 GeV) + Au collisions are
analyzed within the statistical multifragmentation model with the critical
temperature for the nuclear liquid-gas phase transition Tc as a free parameter.
The analysis presented here provides strong support for a value of Tc > 15 MeV.
In the article we research the means for fault detection system set up for NGV-refuelling stations compressor equipment. It is a real-time diagnostics while operation. Equipment technical state is ...estimated in accordance with vibration index analysis. The fault detection system helps to vary frequency till fifteen harmonic components of generated signal and vibration acceleration and gives opportunity to input frequency deviation input at preset range artificially. Here are two ways of measuring channel scheme.
Phys.Rev.C67:011601,2003 The charge distribution of the intermediate mass fragments produced in p (8.1
GeV) + Au collisions is analyzed in the framework of the statistical
multifragmentation model ...with the critical temperature for the nuclear
liquid-gas phase transition $T_c$ as a free parameter. It is found that
$T_c=20\pm3$ MeV (90% CL).
The relative angle correlation of intermediate mass fragments has been studied for p+Au collisions at 3.6 GeV. Strong suppression at small angles is observed caused by IMF-IMF Coulomb repulsion. ...Experimental correlation function is compared to that obtained by the multi-body Coulomb trajectory calculations with the various decay time of fragmenting system. The combined model including the empirically modified intranuclear cascade followed by statistical multifragmentation was used to generate starting conditions for these calculations. The model dependence of the results obtained has been carefully checked. The mean decay time of fragmenting system is found to be 85 +- 50 fm/c.

Phys.Lett. B503 (2001) 256-262 Multiple emission of intermediate-mass fragments has been studied for the
collisions of p, $^4$He and $^{12}$C on Au with the $4\pi$ setup FASA. In the
case of ...$^{12}$C(22.4 GeV)+Au and $^4$He(14.6 GeV)+Au collisions, the
deviations from a pure thermal break-up are seen in the energy spectra of the
emitted fragments: the spectra are harder than calculated and than measured in
p-induced collisions. This difference is attributed to a collective flow with
the expansion velocity on the surface about 0.1 $c$ (for $^{12}$C+Au
collisions).
Nucl.Phys. A709 (2002) 392-414 Multiple emission of intermediate-mass fragments has been studied for the
collisions of p, $^4$He and $^{12}$C on Au with the $4\pi$ setup FASA. The mean
IMF ...multiplicities (for the events with at least one IMF) are saturating at the
value of $2.2\pm0.2$ for the incident energies above 6 GeV. The observed IMF
multiplicities cannot be described in a two-stage scenario, a fast cascade
followed by a statistical multifragmentation. Agreement with the measured IMF
multiplicities is obtained by introducing an intermediate phase and modifying
empirically the excitation energies and masses of the remnants.
The angular distributions and energy spectra from the p-induced collisions
are in agreement with the scenario of ``thermal'' multifragmentation of a hot
and diluted target spectator. In the case of $^{12}$C+Au(22.4 GeV) and
$^4$He(14.6 GeV)+Au collisions, deviations from a pure thermal break-up are
seen in the energy spectra of the emitted fragments, which are harder than
those both from model calculations and from the measured ones for p-induced
collisions. This difference is attributed to a collective flow.
