Abstract
An improved double-differential resonance-dependent scattering kernel is presented and its impact on criticality, Doppler Effect, absorption, and inventory of heavy isotopes for a typical unit cell is confirmed again to be significant. The influence of solid state effects is investigated. The way the resonant crystal lattice model based on a 4-point correlation function differs from the free gas scattering kernel is discussed and the differences are shown to be small.
