Abstract
A microscopic cluster model of the nucleus-nucleus bremsstrahlung based on an extension of the Siegert theorem, i.e., based on the charge density rather than on the current, allows including implicitly a part of the effects of meson-exchange currents. This approach was developed in a previous paper for zero-spin nuclei and applied to the bremsstrahlung. This model is extended to colliding nuclei with nonzero spins and applied to the and bremsstrahlungs. A comparison between the bremsstrahlung cross sections for these mirror systems is made. The importance of the meson-exchange currents on the bremsstrahlungs is discussed by comparing the and components of the bremsstrahlung cross sections obtained in the Siegert approach where these currents are partly included and in the non-Siegert approach where they are fully neglected.
