############################################################################### Maxwellian-averaged cross section data files based on JENDL-3.3 2005/01 ############################################################################### Maxwellian-averaged cross sections (MACS) were calculated from JENDL-3.3. The data were written by the following WRITE statement WRITE(2,10) IZ,IA,LISO,MTI,NTEMP,S2200,SRES1, * (T(K),SIGA(K),sv(K),K=1,NTEMP) 10 FORMAT(5I5,1P2E11.4/(1P3E11.4)) IZ : Atomic number IA : Mass number LISO : Isomeric state number (ground = 0) MTI : Reaction ID number (same as MT number defined in ENDF format) NTEMP : Number of temperature points S2200 : Cross section at 0.0253 eV (barns) SRES1 : Resonance integral above 0.5 eV (barns) T(K) : Temperature kT (eV) SIGA(K) : Average cross section (barn) sv(K) : Reaction rate (cm^3/sec) A blank record separates the data sets. The calculation was made for capture (MTI=102), fission (MTI=18), (n,p) (MTI=103), (n,alpha) (MTI=107). The results were stored in the following files: j33MaxwAv_102.dat capture j33MaxwAv_018.dat fission j33MaxwAv_103.dat (n,p) j33MaxwAv_107.dat (n,a) j33MaxwAvOth.dat some special reactions The files for fission, (n,p) and (n,a) reactions contain only nuclides whose MACS are greater than 1 mb. A report of these sets of MACS is under preparation (as of 2005 Jan.).
