Gl. Klimchitskaya et al., A PROPOSED EXPERIMENT USING A SPHERE WITH AN ECCENTRIC CAVITY FOR HYPOTHETICAL LONG-RANGE INTERACTIONS, International journal of modern physics A, 12(8), 1997, pp. 1465-1482
The constraints are examined which may be obtained for the parameters
of long-range hypothetical interactions by the use of the precise expe
rimental setup created originally for the calibration of accelerometer
s. This setup includes the large rotating steel sphere with a nonconce
ntric spherical cavity in which the strictly homogeneous gravitational
field arises. The field of additional interaction produced by the ato
ms of the sphere, however, is not homogeneous. The essential features
required of the detector of additional interaction which is the torsio
nal pendulum of high sensitivity are discussed. Both the cases of the
Yukawa-type and degree-type hypothetical interactions are investigated
. It is shown that the known-to-date constraints for Yukawa-type inter
actions may be strengthened by a factor of 400 in the appropriate inte
raction range. For the degree-type hypothetical forces decreasing with
distance as r(-3), r(-4) and r(-5) correspondingly the known constrai
nts may be strengthened by the factors of 90, 35 and 20. The conclusio
n is made that with the use of the specially created related setup it
will be conceivable to strengthen the constraints for Yukawa-type inte
ractions up to 4500 times over a wide interaction range.
