Abstract

We examined the ⁴⁰Ca + ²³⁸U reaction experimentally using the Mass-Angle Distribution (MAD) technique and within the Time Dependent Hartree Fock (TDHF) theory, using the TDHF3D code. A new, TDHF based approach has been developed to construct mass distributions as well. The results revealed that the orientation of the heavy deformed prolate nucleus plays a major role in the reaction outcome. It was found that aligned collisions lead to quasifission and short contact times of 5-10 zs, whilst anti-aligned collisions lead to longer contact times (> 23 zs). TDHF accurately predicted the presence of quasifission and the average mass splits in this reaction. The influence of shell effects around ²⁰⁸Pb in the calculated quasifission characteristics was observed in both experiment and theory.
