title: Primarily isotropic nature of photorefractive screening solitons and the interactions between them.
abstract: We present experimental evidence demonstrating that the photorefractive-index change responsible for the formation of photorefractive spatial screening solitons and coherent collisions between them is primarily isotropic in nature, even though the photorefractive medium is inherently anisotropic.
