Dynamical fission calculations show that the post-scission configurations resemble two colinear pear-shaped fragments whose juxtaposed surface bulges subside relatively quickly, as the fragments acquire smoother shapes [1]. The associated rapid speed of the healing bulge surface may boost nucleons in the fragment to energies sufficient for emission. The present study explores this "catapult"...

The problem of scission neutron emission during fission is addressed in a microscopic approach. During scission, the internal degrees of neutrons are coupled to the fast-changing potential. This coupling depends on the time of transition ∆T between a deformed nucleus with a very thin neck and two just separated fragments. Each neutron
becomes a wave packet with components in the continuum and...
