--------
The file includes discrete level scheme data for 644 nuclei from 2-He-4 
to 100-Fm-255. Level energies, spins and parities for 12109 levels are 
included. Some of levels also have gamma-ray branching ratios. Basically 
the level scheme data were taken from ENSDF and were slightly modified to 
be used in JENDL-3 evaluation.
Format
------
Level scheme is stored between a LEVEL record and an ENDLEVEL record: 
	LEVEL
        ...
	ENDLEVEL
In the DATA section, the following data can be stored:
        NO	level number.  A ground state should be 0.
        EL	level energy (MeV).
        J	spin.  For the level energy above where levels can be assumed 
		to be overlapping, J=-1.0. 
        PARITY	parity.  Parity of + and - is represented by 1.0 and -1.0, 
		respectively. For the overlapping state, PARITY = 0.0.
        HL	half-life (sec).
        NG	number of gamma-rays emitted from the level.
        FLVL	level number of final state.
        BR	branching ratio.
        EG	gamma-ray energy (MeV).
If gamma transition data are given, NG, FLVL, BR and/or EG have to be specified
in the form of
	DATA                      ...  , NG (FLVL, BR)
Among these parameter symbols, EL, J and PARITY should be always given.  For 
gamma-ray transition data, in addition to them, NO, NG, FLVL and BR are 
obligatory.  The data should be stored in the increasing order of level numbers 
and level energies.  In the columns from 1 to 9, nuclide name is given in the 
increasing order.
