Evaluation of neutron induced reactions on tungsten isotopes

IAEA NAPC Nuclear Data Section

NEWS

Objective: To re-evaluate neutron induced reactions on W-180,W-182,W-183,W-184 and W-186 isotopes combining available experimental data and benchmark results. Covariance information will be included in evaluated files.

May/2009 : Final evaluations released
