Electron capture in fully ionised nuclei

In summary, electron capture in fully ionized nuclei is a nuclear decay process where an electron is absorbed by the nucleus, resulting in a decrease in the atomic number and the emission of a neutrino. It is significant for stabilizing the nucleus and plays a role in the formation of heavy elements. It differs from other types of nuclear decay and has potential applications in nuclear physics research and the detection of electron neutrinos.

Hello everyone,
What happens if an isotope that normally decays through EC has no electrons at all? For example how does 7Be4+ decay?

If beta+ decay is not possible and there are no electrons around, the isotope becomes stable.

Positron emission is energetically blocked for Be-7, so it becomes stable.

Most heavier nuclei will have the positron emission channel open up.
 

1. What is electron capture in fully ionized nuclei?

Electron capture in fully ionized nuclei is a type of nuclear decay process in which an electron from the innermost shell of an atom is absorbed by the nucleus. This process can only occur in fully ionized nuclei, where all the electrons have been removed, leaving a positively charged nucleus.

2. How does electron capture in fully ionized nuclei occur?

Electron capture in fully ionized nuclei occurs when a proton in the nucleus interacts with an electron from outside the atom. The electron is absorbed by the nucleus, and a neutron is created. This process results in a decrease in the atomic number of the nucleus and the emission of a neutrino.

3. What is the significance of electron capture in fully ionized nuclei?

Electron capture in fully ionized nuclei is significant because it helps to stabilize the nucleus by reducing the number of protons. This process also plays a crucial role in the formation of heavy elements in the universe through the process of nucleosynthesis.

4. How is electron capture in fully ionized nuclei different from other types of nuclear decay?

Electron capture in fully ionized nuclei is different from other types of nuclear decay, such as alpha and beta decay, because it involves the absorption of an electron instead of the emission of a particle. It also results in a decrease in the atomic number of the nucleus, unlike other types of decay where the atomic number either remains the same or increases.

5. What are the potential applications of electron capture in fully ionized nuclei?

Electron capture in fully ionized nuclei has potential applications in nuclear physics research, such as in the study of nuclear structure and the production of radioactive isotopes for medical and industrial purposes. It is also used in the detection and measurement of electron neutrinos, which can provide valuable information about the composition of the universe.
