An approximate method for solving the transport equation, related to the spherical harmonics method and based on two expansions of the angular dependence of the differential particle flux density, one in the forward direction and one in the backward direction. This method is used mainly when there is a marked change of neutron characteristics across a boundary. 2, record 1, English, - double%20spherical%20harmonics%20approximation%20method

Méthode approchée de résolution de l'équation du transport, analogue à la méthode des harmoniques sphériques et fondée sur deux développements du débit de fluence différentiel en fonction de l'angle, dans deux directions opposées. Cette méthode est surtout utilisée lorsque les caractéristiques neutroniques présentent un changement marqué au passage d'une frontière. 3, record 1, French, - m%C3%A9thode%20des%20doubles%20harmoniques%20sph%C3%A9riques
