Abstract
Spaces homogeneous under the action of the quantum SU(2) group are introduced and investigated. These spaces can be considered as noncommutative two-dimensional spheres of different radii. The geometry of the space built from those spheres makes possible one-particle dipole electric transitions with Δl=0.
