Session D40 - Poster Session I.
POSTER session, Monday afternoon, March 12
Exhibit Hall, Washington State Convention Center
We will report on a method for measuring cluster polarizabilities in the gas phase. In this method a beam of clusters traverse a standing wave formed by a laser beam. By measuring the downstream spatial distribution with and without the laser, the polarizability can be determined. To date, the optical polarizability of C_60 at the fundamental wavelength of a Nd:YAG laser (1.064 \mum) has been measured(A. Ballard, K. Bonin, and J. Louderback, J. Chem. Phys. 113), 5732-5735(2000).. We also hope to report on a measurement of the polarizability of C_70 using the same technique.(This work was supported by the National Science Foundation under contract CHE-9420441 and by the Dept. of Energy under contract LLNL/DOE B278815.)
