Measurement of the Casimir force in the range above 5 microns employing a torsion balance |
Abstract _ |
I will report on a new measurement of the Casimir force between a plane conducting surface and spherical conducting surface, in the range of separation 3-10 microns, employing a torsion balance. The results show a deviation from the zero temperature force law and this deviation is consistent with the finite temperature corrections, indicating that this could be the first measurement in which the finite temperature correction is seen. The need to subtract out large electrostatic effects limits the accuracy of our measurements. |
