c### the code was changed to make it compatible with NAG f95 compiler (Linux).
c### Changes are marked by "imos"; I.Moskalenko 2/15/2000

SUBROUTINE YIELDX(IZ, IA, JZ, JA, EJ, QJ) ! Dec 1999
C*****************************************************************************
C IZ IA : charge and mass of the nucleus
C JZ JA : charge and mass of spallation product (He-6 and heavier)
C EJ : energy in MeV/n
C QJ : cross section in mb
C
C The code was developed at NRL by Rein Silberberg and C. H. Tsao.
C It is designed for quick estimation of cross sections only.
C The results are not suited for physical interpretation.
C
C This latest version is undertaken with NASA's sponsorship
C and the assistance of Dr. A.F. Barghouty at the Roanoke College
