 Total level densities for Gilbert-Cameron and back-shifted Fermi gas models
         (Provided by A. V. Ignatyuk, 29 October 1997)
  ***************************************************************************

Contents
--------
These files contain the level density parameters for the Gilbert-Cameron 
approach and for the back-shifted Fermi gas model. The parameters are 
obtained by fitting the corresponding formulas both to neutron resonance
spacings and to cumulative numbers of low-lying levels evaluated by the 
Obninsk group.

Each row contains the following data: 

Z   :  Atomic number of compound nucleus, 
EL  :  Element symbol of compound nucleus,
A   :  Mass number of compound nucleus, 
I   :  Spin of the ground state for target nucleus, 
Bn  :  Neutron binding energy of compound nucleus in MeV, 
a   :  Level density parameter of the Fermi gas formula in 1/MeV,
del :  Pairing correction in MeV for the constant temperature model in 
       Gilbert-Cameron approach and for the Fermi gas formula in the
       back-shifted model,
Do  :  Average resonance spacing in eV,
Uo  :  Excitation energy corresponding to the estimated number of
       low-lying levels in MeV,
No  :  Cumulative number of low-lying levels below Uo .
