Energetics of Nuclear Reactions
Reaction Types and Mechanisms
Nuclear Reaction Cross Sections
Compound Nuclear Reactions
Solve of laboratory T
A for mass
sl is partial cross section of given angular momentum l
Neutron Capture; S-process
ZA = charge of species A
µ = molal ionic strength
RA = hydrated ionic radius in Å (from 3 to 11)
First estimation of activity
ij = specific ion interaction term
Experimental Data shows change in stability constant with ionic strength
Ion Specific Interaction Theory
Cm-Humate at pH 6
Must look at equation!
Other species may need to be considered. If total uranium concentration is low enough, binary or tertiary species can be excluded.

Ksp really best for slightly soluble salts
