SUBROUTINE SPHSX5(IPAPX,RECNAM,NREA,NGROUP,NISOF,NISOP,NL,INDX,
1 NOMREA,SIGS,SS2D,XS,LXS)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Recover the cross sections of an elementary calculation and single
* mixture in an Apex file.

*Author(s): A. Hebert
*
*Parameters: input
* IPAPX pointer to the Apex file.
* RECNAM character identification of calculation.
* NREA number of reactions in the Apex file.
* NGROUP number of energy groups.
* NISOF number of fissile isotopes.
* NISOP number of fission products.
* NL maximum Legendre order (NL=1 is for isotropic scattering).
* INDX position of isotopic set in current mixture (=-2: residual
* set; -1: total set; >0 isotope index).
* NOMREA names of reactions in the Apex file.
* LXS existence flag of each reaction.
*
*Parameters: output
* SIGS scattering cross sections.
* SS2D complete scattering matrix.
* XS cross sections per reaction.
* LXS existence flag of each reaction.
