The report analyzes the optomechanical interaction of a Gaussian beam and a silicon nanoparticle in a hybrid anapole state. To study the particle scattering in the Gaussian beam waist, as well as to confirm the appearance of a hybrid anapole state, a multipole decomposition was carried out. We made calculations of the optical forces acting on the particle along different directions depending on the relative position of the light beam and the particle. The pressure and gradient components of force were analyzed separately. In addition, the torque acting on the anapole and scattering particles at the center of the beam waist was calculated. It is shown that the torque can change sign if the particle is at anapole. #CSOC1120.
