Description naranjo 2005-05-27 11:54:33 CEST 
The inelastic neutron scattering cross section data for chlorine contains a NaN,
  leading to significant discrepancies.  This was first reported elsewhere:

Hi,  thank you for the posting. It is a known problem, but I can do little
about it. The G4NDL 3.7 data library has severe problems. The data are very
old, and still buggy at the same level as for example ENDF/B was in 1988. It
also has a copyright problem, and we no longer can distribute the library. I am
currently working to overcome most of these problems, by creating a fresh
evaluation, but this takes some time...

Many greetings,

Hans-Peter.

G4NDL v3.8 is released and
Inelastic/CrossSection/17_nat_Chlorine is recreated from
Cl-NAT (neutron) from ENDF/B-VI Tape 101.
"NaN" enetry has gone with this update.
