Abstract
As we go to press, we have received the following radiogram, dated Sept. 28, from Sir C. V. Raman, F.R.S., and S. Bhagavantam: “Experimental demonstration of spin of light.—The depolarisation of Rayleigh scattering of monochromatic light in carbon dioxide gas does not diminish to one quarter of its value when spectroscopically separated from rotational scattering, as demanded by existing theories of radiation. The actual observed diminution, from 10 per cent to 6 per cent, is quantitatively explicable, assuming that common light consists of spinning quanta possessing one Planck unit of angular momentum.—C. V. Raman and S. Bhagavantam.”
