Absorption of a circularly polarized light beam without an azimuth phase structure in a dielectric is calculated in the frame of the standard electrodynamics. We calculate a transfer of energy, momentum, and angular momentum to the dielectric. The calculation shows that the force acting on the dielectric does not have a surface term and the angular momentum flux in the beam equals to two power of the beam divided by frequency. This results contradict an experiment of A. Bishop et al. (PRL, 92, 198104), a paper of R. Loudon (PRA, 68, 013806), and another part of standard electrodynamics, which predicts the flux equals to power of the beam divided by frequency. At the same time the last part of the electrodynamics contradicts to the classical Beth's experiment (PR, 50, 115). To correct this part of the standard electrodynamics we introduce a spin tensor. The corrected electrodynamics is in accordance with our calculation and with the Beth's experiment. But we cannot help the Bishop's and Loudon's results.
