    We present both theoretical and experimental study of longitudinal optical binding between two nanopatricles or microparticles placed in two counter-propagating Bessel beams. We consider coherent linearly polarized beams and we rotate polarization of one beam so that both beams interfere or do not interfere. We present an experimental demonstration of the remarkable changes in the behaviour of both spheres leading to freezing of the structure if both beams interfere.
