    Notes: Abstract: Long-Range Alpha (LRA) emission probability is studied using a one dimensional sudden approximation model. The probability of the energy transfer between the scissioning nucleus and the LRA particle as well as the LRA angular distribution are discussed for several elongations and for several mass splits at scission. Finally, it is shown that a comparison between the calculated LRA emission probability and the corresponding experimental data allows a determination of the Q -value at the scission point.

    Notes: Abstract The time-dependent Schrödinger equation for the fission of213At through a one-dimensional potential barrier was solved numerically within a finite spatial grid. Several initial quasi-stationary vibrational states at and below the top of the barrier were considered. The time dependence of the decay rate γ(t) was calculated. The non-exponential evolution of the process in the very early stages (≦10−20 s) differs considerably from the asymptotic (stationary) one. Fission is therefore delayed by the sum of this preexponential time, of the tunneling time and of the time necessary for the descent from the outer turning point to the scission point. These non-dissipative quantum times play the same role as the classical transient times usually included in the analyses of experimental data on pre-scission emission of light particles andγ rays.
