Abstract
An intrafield symbiotic form of the bright and the dark solitons, termed a symbion, is found in the framework of the Hartree approximation for a multidimensional nonlinear Schrödinger equation. Algebraically, the symbion can be expressed by the product of the two fields; its eigenvalue and stationary field distribution are determined analytically in a self-consistent fashion. The error due to the approximation is analyzed.Keywords
