Fission mode calculations for lighter actinides — •L. Demattè¹, F.-J. Hambsch¹, and S. Oberstedt² — ¹JRC-IRMM, Retieseweg, B-2440 Geel, Belgium — ²ILL, F-38042 Grenoble, France

Fission mode calculations have been started for the lighter actinides in the frame of the multi-modal random neck-rupture model of Brosa et al. [1]. This is done in view of understanding the drastically changing charge distributions found in the recent GSI-experiments [2]. The calculations are in progress for the isotopes ^220,226,230Th and ²²⁶Ac. First results will be shown.
