3. DESCRIPTION OF PROBLEM OR FUNCTION

COGEND is used to generate nuclear decay scheme data in standard ENDF/B-IV or ENDF/B-V format,  as required by the user. Output consists of a printed summary of the input data, a listing of the resulting ENDF/B format data and the ENDF/B data produced on the required medium - punched cards, magnetic tape or disk. COGEND includes routines to calculate from input spectral data values of:
i)   Mean alpha and gamma energies
ii) Mean beta energies - allowed to 4th unique forbidden transitions by means of an "exact" method
iii) Conversion electron energies and intensities
iv)  K-, L- and M-shell capture ratios in electron capture decay
v)   K-, L- and M-shell Auger electron energies and intensities
vi)  K-, L- and M-shell X-ray energies and intensities
vii) Energy of the recoil nucleus in alpha decay
viii) Internal bremsstrahlung emission associated with beta decay.
    
In addition, COGEND automatically summarises details of the decay scheme, in an easily readable form, in the comments section of the ENDF/B output.
  
This new version of COGEND is used to generate nuclear decay scheme data in standard ENDF-6 format. Output consists of a printed summary of the input data, a listing of the resultant ENDF-6 format data and the ENDF-6 data.
  
This current version of COGEND has been further developed to cover (beta-n) and (beta-a) decay.
NEA-0915/03
Version NEA-0915/03 is the translation to Fortran 90 of version NEA-0915/02.
Some small modifications have been introduced into the Fortran source code to improve its portability.
Makefiles have been included for use with g95 compiler.
