Abstract：
The structure, operation principle, and performance of the bi-dimension position sensitive avalanche chamber (BPAC) used in the study of fusion fission induced by heavy ions at the near- and sub-barrier energy regions are described.
The fold angle distribution of fragments in different angle regions for the 84 MeV (E_cm) ¹⁶O+²³²Th reaction system was obtained by using BPAC, from which the angle distribution of transfer-fission fragments has been distinguished from that of compound nucleus fission fragments. It is thereby certified that transfer Hssion is not the reason for anomalous anisotropies of fragment angular distribution. Meanwhile experimental results supported the pre-equilibrium fission model, in the frame of which the anomalous anisotropies of fragment distribution were explained.
