This experiment was performed at a pressure of 3x10^{-8} Torr with hollow glass sphere of 41.3 mcm radius. Special attention is paid to electrostatic calibrations including the problem of electrostatic patches. All calibration parameters are shown to be separation-independent after the corrections for mechanical drift are included. The gradient of the Casimir force was measured in two way","authors_text":"A. A. Banishev, C.-C. Chang, G. L. Klimchitskaya, R. Castillo-Garza, U. Mohideen, V. M.
