cluster decay

The model was the first to be used to predict measurable quantities in cluster decay.

He contributed to the theory of heavy particle radioactivity (Cluster decay).

He published the most frequently-cited paper in the field of cluster decay in 1980.

Cluster decay was shown to be a superasymmetric spontaneous fission process.

This is not cluster decay, as the fission products may be split among nearly any type of atom.

In 2006 the barrier shape of some cluster decay modes were obtained by using the macroscopic-microscopic method.

Cluster decay is one of the rare examples of phenomena predicted before experimental discovery.

Spontaneous fission ends up with a probabilistic distribution of daughter products, which sets it apart from cluster decay.

More than 150 cluster decay modes have been predicted before any other kind of half-lives calculations have been reported.

However, there are trace amounts in nature of the radioactive isotope fluorine-23, which occurs via cluster decay of protactinium-231.

For heavier emitted clusters there is otherwise practically no qualitative difference between cluster decay and spontaneous cold fission.

The main experimental difficulty in observing cluster decay comes from the need to identify a few rare events among an enormous number of background alpha particle.

The first two Conferences at which cluster decay modes were discussed were Varna in 1985 and Kyoto 1988.

Cluster decay, like alpha decay, is a quantum tunneling process: in order to be emitted, the cluster must penetrate a potential barrier.

His ASAF model provides a unified approach of cold fission, cluster decay and alpha decay.

Occasionally it decays by the unusual route of cluster decay, emitting a nucleus of O and producing stable Pb.

In cluster decay for a given radioisotope, the emitted particle is a light nucleus and the decay method always emits this same particle.

A unified approach of Cluster decay, alpha decay and cold fission was developed by Dorin N Poenaru et al.

In other types of radioactive decay, such as cluster decay, larger species of nuclei are ejected (for example, neon-20), and these eventually become newly-formed stable atoms.

In a phenomenon called cluster decay, specific combinations of neutrons and protons other than alpha particles (helium nuclei) were found to be spontaneously emitted from atoms.

Alpha decay is the most likely cluster decay because of the combined extremely high binding energy and relatively small mass of the helium-4 product nucleus (the alpha particle).

The Geiger-Nuttall Law has even been extended to describe cluster decays [1], decays where atomic nuclei larger than Helium are released, e.g. Silicon and Carbon.

A possible stronger decay mode for the heaviest superheavies was shown to be cluster decay by Dorin N Poenaru, R.A. Gherghescu, Walter Greiner.

In contrast, Ne (the chief primordial isotope made in stellar nucleosynthesis) is not known to be nucleogenic or radiogenic (save for cluster decay production, which is thought to produce only a small amount).
