New Features of the Monte-Carlo Code MOCADI

MOCADI, the Monte-Carlo code for tracking of ions in ion-optical systems with non-Liouvillian elements, has been extended. New event generators for targets were added besides projectile fragmentation. General twobody kinematics with possible excitation energy of target and projectile nucleus and nuclear fission with different parametrizations of the total kinetic energy distribution of the fragments were included. Both cases lead to a complicated distribution with correlation of the fragments in the secondary beam. With MOCADI the acceptance in a beamline of complicated geometry can be taken into account as higher order optics given by transfer matrices is combined with the real apertures in the beamline. Also spontaneous nuclear decay along the flight path is now possible with a realistic distribution in time. The possibility to handle also electrostatic beamline elements correctly, makes MOCADI also applicable for velocity filters like SHIP and for fusion or heavy ion transfer reactions.
