Dear Charles,
133 Cs is one of those nuclides I like very much to work with.
The quadrupolar nucleus has a high spin number (7/2) resulting in
long relaxation times, e.g. for the cation Cs+ in water at infinite
dilution 1/T1= 0.086 s^-1.(see e.g. my table in the BRUKER Almanach.)
In the former Hertz group we investigated the relaxation of the ionic nucleus
in many solvents. For water see e.g.: Ber. Bunsenges. Phys.Chem.
Vol.78,493,(1974)
The sensitivity is rather high and therefore you should not expect special
problems.
Best regards,
Manfred
