Body text

Q values for every reaction

fission yields

product yields

isotope masses

branching ratios

gamma emission (discrete, cotinuum ....)

delayed neutron emission

Body text

Angular distributions

neutrons and photons in outgoing channel (can be correlated)

thermal scattering laws

resonance parameters (for resolved resonance region)

atomic relaxation data (after photoelectric absorption m k 

• electron shell structure
• fluorescence yields
• Auger yields
• x-ray transition probabilities
• binding energies

Cross sections

total, elastic, inelastic, capture, fission,
(n,2n), .... hundreds of energy dependant reactions

coherent scattering, incoherent scattering, pair production ....

for several temperatures
