This is version 1.1 of the sublibrary of giant dipole resonance parameters 
for the gamma-rays (GDP), a part of the Chinese Evaluated Nuclear Parameter 
Library (CENPL).  
The data file contains  the giant dipole resonance parameters for the 
gamma-ray strength function. These parameters of Lorentz curves fitted 
to total photoneutron cross section data were compiled by Samuel S. Dietrich 
and Barry L. Berman [1] for 102 nuclides raging from 51-V to 239-Pu in 1987 
and were estimated for the nuclides 12-C, 14-N, 16-O, 27-Al and 28-Si by us 
in 1995 [2].
Format
------
Each record of the file contains Z, EL, A, NL, NG, E1, CS1,GW1, E2, CS2, GW2, 
REF, and No as defined below:
     Z  : charge number, column 1-3.
     EL : element symbol, column 4-6.
     A  : mass number, column 7-10.
     NL : it gives how many sets of data for same nucleus, column 11-13.
     NG : for NG=1, single peak; for NG=2, double peaks, column 14-16.
     E1 : peak energy of the first peak, column 17-23.
     CS1: peak cross section of the first peak, column 24-30.
     GW1: peak full width of the first peak at half-maximum, column 31-36.
     E2 : peak energy of the second peak, column 37-43.
     CS2: peak cross section of the second peak, column 44-50.
     GW2: peak full width of the second peak at half-maximum, column 51-56.
     REF: publication reference, bibliographic information is given
          in a chronological listing following the table, column 57-63.
     No:  the order number, column 68-71.
   
          The units for the listed quantities are given with the respec-
          tive subunits headings.
