In two recent papers, it has been demonstrated that, beside usual scattering and optical forces, new optical forces and terms are exhibited when a Rayleigh particle is illuminated by an off-axis Bessel beam. Namely, (i) axicon optical forces are associated with scattering optical forces and (ii) additional axicon terms are associated with gradient optical forces. These extra-axicon forces and terms are zero when the axicon angle is zero and/or (most often) when an on-axis configuration is considered rather than an off-axis configuration. This study was devoted to longitudinal forces. The present paper is devoted to transverse forces and demonstrates the existence of newly additional axicon forces associated to both the usual scattering and gradient forces. Again, these new extra-axicon forces are zero when the axicon angle is zero and/or when an on-axis configuration is considered rather than an off-axis configuration.

在最近的两篇论文中，已经证明，当用离轴贝塞尔光束照射瑞利粒子时，除了通常的散射力和光学力之外，还显示出新的光学力和项。即，（i）轴锥视光学力与散射光力相关，并且（ii）附加轴锥视光学术语与梯度光力相关。当轴锥锥角度为零时，这些轴外锥力和项为零，和/或（通常）在考虑轴上配置而不是轴外配置时，（通常）。这项研究致力于纵向力。本文致力于横向力，并演示了与常规散射力和梯度力相关的新的附加轴锥力的存在。再次，
