MASS-ASYMMETRIC BREAKUP IN THE EXTENDED FINITE-RANGE MACROSCOPIC MODEL

Using the Cassinian ovaloid as fission shape both in symmetry and asym metry, including Yukawa-plus-exponential finite range interaction and diffused surface, the rotating finite-range Casinian ovaloid liquid dr op model is developed. The dependence of the fission barrier heights o n mass-asymmetry and on angular momentum is studied for the compound n uclei In-112, Tb-159 and Bi-209. The predicted asymmetric fission barr iers and mass yields are compared with experimental data obtained from the deexcitation of hot composite nuclei by complex fragment emission .
