The first ENDL validation meeting

1. The first ENDL validation meeting Koi, Tatsumi SLAC

2. The first ENDL validation meeting just held at SLAC on Feb 18th. • Participants from national labs around SF bay. • From field of underground physics and nuclear physics. • Sharing knowledge and validation results and reflect further development of G4ENDL interface.

3. Found problems in C(n,n)C* • n+C -> n + C* -> n + 3 alpha n + Be8 + alpha -> n + 3 alpha • n+C -> n + 3 alpha cross section is provide by ENDF file in tricky way. But no ratio between above channel. • Potentially we can use evaporation model for this? • This channel is important for diamond detector. • Same validations should be done with NeutronHP • Possibility for developing direct interface to ENDF files • We will have this meeting regularly and next will held on March 11th
