3. DESCRIPTION OF PROBLEM OR FUNCTION - ATHENA4 computes form factors 
for inelastic scattering calculations,  using single-particle wave 
functions that are  eigenstates of motion in  either a Woods-Saxon 
potential well or a harmonic  oscillator well.  Two-body forces of 
Gauss,  Coulomb,  Yukawa,  and  a sum  of  cut-off  Yukawa  radial 
dependences are available. 


4. METHOD OF SOLUTION - 


5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - Maxima of - 
   100 wave function components 
    10 interaction components 
The reduced  matrix elements of  the one-body  multipole operators 
may be included  automatically in the wave  function coefficients. 
Non-local effects  on the  wave functions may  be included  in the 
local energy approximation. 


6. TYPICAL RUNNING TIME - About 2 minutes are required for the sample 
problem. 


7. UNUSUAL FEATURES OF THE PROGRAM - 


8. RELATED AND AUXILIARY PROGRAMS - ATHENA4 is a revised and updated version of the original ATHENA code. It can punch the form factors on cards in a format suitable for input to the DWBA code JULIE.
