Time scales for fission at finite temperature
The concept of the ”transient effect” is examined in respect of a ”mean first passage time”. It is demonstrated that the time the fissioning system stays inside the barrier is much larger than suggested by the transient time, and that no enhancement of emission of neutrons over that given by Kramers’ rate formula ought to be considered.
متن کاملHidden systematics of fission channels
It is a common procedure to describe the fission-fragment mass distributions of fissioning systems in the actinide region by a sum of at least 5 Gaussian curves, one for the symmetric component and a few additional ones, together with their complementary parts, for the asymmetric components. These components have been attributed to the influence of fragment shells, e.g. in the statistical sciss...
متن کاملTime-frequency or time-scale representation fission and fusion rules
Time-frequency representations are important for the analysis of time series. We have developed an online timeseries analysis system and equipped it to reliably handle re-alignment in the time-frequency plane. The system can deal with issues like invalid regions in time-frequency representations and discontinuities in data transmissions, making it suitable for on-line processing in real-world s...
متن کاملFission–fusion populations
obese. Applying an understanding of nutritional and evolutionary theory to the modern human nutritional dilemma has turned out to be very enlightening indeed. Who have been your most important mentors? Two people have had the greatest impact on my career. The fi rst was the late Reg Chapman as my PhD supervisor. Reg and his wife Liz Bernays were inspiring, selfl ess and incredibly tolerant. I c...
متن کاملMitochondrial fission and fusion.
Mitochondria are highly dynamic cellular organelles, with the ability to change size, shape and position over the course of a few seconds. Many of these changes are related to the ability of mitochondria to undergo the highly co-ordinated processes of fission (division of a single organelle into two or more independent structures) or fusion (the opposing reaction). These actions occur simultane...
