---------
The code LOSALAMOS_ANALYTICAL.FOR (original name LINMOM.F) implements the
Chadwick-Oblozinsky continuum angular distribution theory, See Phys. Rev.
C50, 2490 (1994). The sample input corresponds to Figure 1 of this reference,
reaction 45 MeV 90Zr(p,xn), eout=20 MeV:

c Input paramters as follows: (ALL FREE FORMAT)
c ein, eout = incident and emission energies
c bindin and bindout = sparation energies for projectile and ejectile
c from the composite nucleus
c efermi = Fermi energy (35 MeV)
c dsde = angle-integrated preequilibrium cross section at this emiss. energy
c amass = target A value
c nstages = number of preequilibrium stages to be included
c rat(i) = the relative contribution of the preequilibrium stage i
c to the total preequilibrium spectrum, for emission energy eout.
