Background
----------                        
LIVERMORE.DAT file represents the Livermore Biological File of Discrete 
Levels. It was derived in 1993 by looking at different sets of information, 
particularly Fay-Selove's compilations, for modeling nucleon-induced 
reactions on C and O. Therefore, information in the file is not complete, 
in the sense that not every nuclide for A < 18 is included - only those 
needed for these calculations. However, a large fraction of the nuclides 
are included. 

Format
------
The columns have the following meaning:

 ID   = nuclide indicator = 1000*Z + A 

 N-up = number of the maximum level below which information on E, J, pi of 
        levels was judged "complete".

 E-up = Equivalent excitation energy below which information on E, J, pi of 
        levels was judged "complete".

NOTE 
----
 The value of E-up listed below is the output from the level density 
 matching subroutines, and is obtained from an algorithm in that routine
 which does the matching of "continuum" to "discrete" level regions.
 In most cases, E-up is slightly higher than the real excitation energy
 of the level N-up. Don't worry about this! You should just treat E-up 
 as the energy below which levels should be included. Any levels above 
 this energy can be thrown away.

 In general don't put much weight on the N-up values listed; rather, use 
 the E-up values to decide where to truncate your discrete schemes.
