A microscopic model for nuclear dynamics has been formulated and applied to the collisions between heavy ions. It may be viewed as an extension of the collisionless time‐dependent Hartree–Fock ( TDHF ) method to include nucleon‐nucleon collisions. The collision term is written in the form of a time relaxation. The relaxation time is obtained from separate calculations. Some results are shown for the collisions between two 16 O nuclei. The computations require a storage of several million words and require a super‐computer. Calculations have been done on the John von Neumann Center ( JVNC ) CYBER ‐205. Future calculations are planned on the JVNC ETA‐10.
