AbstractWe present preliminary results on a method used to determine the differential scalar polarizability Aao of the clock transition of the 88Sr+ ion optical frequency standard. The method is based on the relation that exists between Aao and the trap frequency 00 at which the micromotion shifts cancel. Aa0 is important not only for cancellation of the micromotion shifts but also for the evaluation of the blackbody radiation shift. The decrease in the uncertainty of Aa0 obtained reduces the evaluated blackbody radiation shift uncertainty of the NRC 88Sr+ ion to the 1x 10-11 level.
