Jr. Peterson et W. Xu, STABILIZATION OF DIVALENT CALIFORNIUM IN CRYSTALLINE STRONTIUM TETRABORATE, Journal of radioanalytical and nuclear chemistry, 203(2), 1996, pp. 301-307
The divalent oxidation state of californium (Cf) has been stabilized i
n crystalline SrB4O7. The ability to generate this less-stable oxidati
on state in an oxide matrix is significant. Factors promoting this sta
bilization have been determined. Access to this divalent state and tho
se of many other lanthanide and actinide elements via a rather straigh
tforward laboratory procedure now facilitates their study and characte
rization.
