P. 596-602Abstract: Results of studying the Umov effect for nonspherical particles large as compared to the incident radiation wavelength are presented. The study is carried out for particles with the maximum size of 100, 140, 170, and 200 μm. The results have been obtained for 210 different refractive indices whose real part varied from 1.3 to 1.6 with a step of 0.5 and the imaginary part varied within the range from 0 to 0.1344. It has been found that the Umov effect occurs for all abovementioned particles provided that the imaginary part of the refractive index is less than 0.001
