compound nucleus

This collision forms a compound nucleus which is in an excited state.

Attention is also drawn to the importance for heavy ion reactions of cluster states in the compound nucleus.

A compound nucleus may be formed, leading to additional neutrons being emitted more slowly.

The ablation stage of the fragmentation is treated as a compound nucleus evaporation.

A compound nucleus is a loose combination of nucleons that have not yet arranged themselves into nuclear shells.

The below table contains various combinations of targets and projectiles that could be used to form compound nuclei with atomic number 117.

The excited quasi-bound nucleus is called a compound nucleus.

In the young spleen, macrophages may also be found, each containing numerous nuclei or one compound nucleus.

Examples of such systems are compound nuclei, excited complex atoms, ions, atomic clusters and molecules.

Capture involves the addition of the neutron to the uranium nucleus to form a new compound nucleus.

His hypothesis was that an incoming particle would strike the nucleus and create an excited compound nucleus.

Compound nucleus formation was assumed up to a bombarding energy of 50 MeV, with direct interaction as the mechanism at higher energies.

This prompted Bohr to create a new theory of the compound nucleus in 1936, which explained how neutrons could be captured by the nucleus.

Upon neutron capture, the compound nucleus emits more easily detectable radiation, for example an alpha particle, which is then detected.

For other compound nucleus phenomena other than nuclear evaporation, it would be considered as the mathematical equivalence of the Fermi gas model under higher excitation.

Mathematically, it is described as a Breit-Wigner function, owing to the resonant nature of the production of the compound nucleus.

The excitation energy within the compound nucleus is formed from the binding energy of the thermal neutron with the target nucleus.

These are processes that create compound nuclei at low excitation energy ( 10-20 MeV, hence "cold"), leading to a higher probability of survival from fission.

Neutrons may be captured by non-fissile nuclei, and some energy is produced by this mechanism in the form of gamma rays as the compound nucleus de-excites.

Several experiments have been performed between 2000-2004 at the Flerov laboratory of Nuclear Reactions studying the fission characteristics of the compound nucleus Ubb.

Similar shifts have been detected in the 7Li(d,αn)4He reaction by Heggie and Martin, who explained the directional correlation effects in terms of a compound nucleus model.

The strong and weak forces are nuclear forces that act only at very short distances, and are responsible for the interactions between subatomic particles, including nucleons and compound nuclei.

Fusion reactions utilizing Ca nuclei usually produce compound nuclei with intermediate excitation energies ( 30-35 MeV) and are sometimes referred to as "warm" fusion reactions.

The direct synthesis of the nucleus Fl by a fusion-evaporation pathway is impossible since no known combination of target and projectile can provide 184 neutrons in the compound nucleus.
