Spherical field in rotating space in 5D
A geodesic motion in rotating 5D space is studied in framework of Kaluza-Klein theory. A proposed phenomenological model predicts basic properties of the Pioneer-effect, namely, a) constant additional acceleration of apparatus on distance from 20 to 50 a.e., b) its increase from 5 to 20 a.e., c) observed absence of one in motion of planets.
