Abstract :
Summary form only given. Most of the data for the atomic polarizability of neutral metal vapor is theoretically calculated as opposed to experimentally measurements. In this paper we present experimentally measured values for the polarizability of neutral vapor generated by exploding wires. The polarizability P, index of refraction /spl eta/ and the neutral vapor density n can be related by the expression /spl eta/=1+2/spl pi/nP. X-pinch backlighting results give the line-integrated neutral vapor density and, assuming azimuthal symmetry, yield the neutral density as a function of radius. Again assuming azimuthal symmetry, the line-integrated interferometry measurements are inverted to give /spl eta/ as a function of position.
