LOSALAMOS.readme Code for analytical calculation of angular distributions using linear momentum approach (Provided by M.B. Chadwick, 15 September 1997) **************************************************************
Contents --------- 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:
