A survey of some results in the modern microscopic theory of properties of 
nuclear reactions with gamma-rays is given. First of all, we discuss the impact 
of  phonon  coupling  (PC)  on  the  photon  strength  function  (PSF)  because  the 
most  natural    physical  source  of    additional  strength,    that  was  found  for  Sn 
isotopes  in  the  recent  Oslo  group  experiments  [1]  and  could  not  be  explained 
within the microscopic HFB+QRPA approach [2], is the microscopic PC effect. 
In  order  to  check  this  statement,  the  self-consistent  version  of  the  Extended 
Theory  of  Finite  Fermi  Systems  [3]  in  the  Quasiparticle  Time  Blocking 
Approximation,  or  simply  QTBA,  was  applied  (see  Ref.  [4]).  It  uses  the  HFB 
mean  field  and  includes  both  the  QRPA  and  PC  effects.  Only  the  known 
parameters of the Sly4 force were used in the calculations. With our microscopic 
E1 PSFs in the EMPIRE3.1 code, the following properties have been calculated 
for  many  stable  and  unstable  even-even  Sn  and  Ni  isotopes  [4–7]:  1)  neutron 
capture  cross  sections,  2)  corresponding  neutron  capture  gamma-spectra,  
3)  average  radiative  widths  of  neutron  resonances.  In  all  the  considered 
properties, the PC contribution turned out to be significant, as compared with the 
QRPA one, and necessary to explain the available experimental data. The very 
topical question about the M1 resonance contribution to PSFs is also discussed. 
Secondly,  as  in  order  to  calculate  the  above-mentioned  properties  it  is 
necessary to use the nuclear level density models,  we  also discuss the modern 
microscopic models based on the self-consistent HFB method, for example, see 
[8], and show their better applicability to explain experimental data as compared 
with the old phenomenological models. 
The  use  of  these  self-consistent  microscopic  approaches  is  of  particular 
relevance for nuclear astrophysics and also for double-magic nuclei.

QUANTUM CHAOS IN NUCLEAR PHYSICS

E-mail: [e-mail] 
 
Contrary  to  numerous  guesses  concerning  quantum  chaos,  the  definition  is 
given  of  both  classical  and  quantum  chaotic  systems  as  a  consequence  of 
Liouville-Arnold theorem [1–3]. Thus quantum chaotic system with N degrees 
of  freedom  should  have  M  <  N  independent  first  integrals  of  motion  (good 
quantum numbers) defined by the system’s Hamiltonian symmetry.  
Therefore  any  nuclear  system  besides  deuteron  is  in  principle  chaotic. 
However in each case one should look for the approximate integrals of motion 
and  the  symmetries  of  the  model  Hamiltonian 
0
H
  generating  these  integrals. 
The degree of chaos in each case is defined by the dimensionless parameter  
spr
0
/ D
  
, 
where 
spr
  is the spreading width of the model Hamiltonian eigenfunctions over 
the eigenstates of the actual Hamiltonian, while 
0
D
 is level spacing of the model 
Hamiltonian.  
For 
1
 
  the  traces  of  the 
0
H
  symmetries  are  quite  obvious  (soft  chaos  —
quantum analogue of the classical KAM theorem). A good example is given by 
the  maxima  of  the  neutron  strength  function  which  are  the  traces  of  the 
symmetries  of  the  nuclear  mean  field  which  are  destroyed  by  the  
nucleon-nucleon residual interactions. 
For 
1
 
  all  the  traces  of  the 
0
H
  symmetries  are  lost  (hard  chaos).  An 
example  is  given  by  the  black  nucleus model  and  by  Wigner’s  random  matrix 
approach. 
For  the  shell-model  Hamiltonian 

increases  with  the  system’s  excitation 
energy 
*
E
 as 
spr
2W
 
, where W is the magnitude of the imaginary part of the 
optical  model  potential.  However 

  remains  smaller  than  unity  even  for  
*
E
  about  50  MeV.  Therefore  the  shell-model  basis  serves  a  good  first 
approximation in many calculations of the nuclear properties. Actually 

 is the 
main  (if  not  the  only)  small  parameter  which  makes  possible  the  majority  of 
numerical calculations in nuclear physics.

CENTRALITY AND MULTIPARTICLE PRODUCTION  
IN ULTRARELATIVISTIC NUCLEAR COLLISIONS

Understanding of the initial conditions of nucleus-nucleus and proton-nucleus 
collisions at high energies is important for any analysis and characterization of 
the expected quark-gluon plasma  formation. Measurements of fluctuations and 
correlations of global observables allow studying a broad region of QCD phase 
diagram. Interpretation of experimental data requires information about impact 
parameter and the number of participating nucleons. In this report we present the 
critical review of widely applied methods of centrality determination based on 
the Glauber model.  
Using  MC  simulations  we  analyze  the  consistency  of  the  concept  of 
centrality  in  the  cases  of  pA  and  AA  collisions  for  heavy  and  light  ions  and 
present  a  method  for  the  numerical  qualification  of  the  centrality  estimators. 
This allows to select the classes of events where background fluctuations related 
to  event-by-event  variance  in  the  impact  parameter  and/or  the  number  of 
nucleons-participants are minimized.  
This  approach  is  checked  in  non-Glauber  Monte  Carlo  model  with  string 
fusion [1]  by  studying  the  dependence  of  multiplicity  fluctuations  and 
correlations on the width of the centrality class.  
By model calculations [1, 2] we also obtained that the account of the  energy-
momentum conservation in soft particles production leads to noticeable decrease 
in  the  number  of  nucleon  collisions  (N
coll
)  in  Pb-Pb  and  p-Pb  interactions 
relative to Glauber model values. Similar effects are intrinsically present in the 
models [3, 4] which aim to describe consistently the collisions of small (pp) and 
large (AA) systems. We conclude that the decrease in N
coll
 is important for low 
transverse  momentum  phenomena,  contrary  to  rare  processes  where 
approximate  Glauber  scaling  remains  applicable.  Overall,  the  results  suggest 
reconsidering the general use of Glauber normalization of the multiplicity yields 
in experimental studies.
