40 Facts About Electron Capture

What is Electron Capture?

Electron capture is a fascinating process in nuclear physics where an atomic nucleus absorbs an inner orbital electron. This process changes a proton into a neutron and emits a neutrino. Let's dive into some intriguing facts about this phenomenon.

1. 01

   Electron capture is also known as K-capture because it often involves an electron from the K-shell, the closest shell to the nucleus.

2. 02

   This process reduces the atomic number of an element by one but keeps the mass number unchanged.

3. 03

   Neutrinos emitted during electron capture are nearly massless particles that rarely interact with matter.

4. 04

   Electron capture is a type of beta decay, specifically inverse beta decay.

5. 05

   Proton-rich nuclei often undergo electron capture to achieve a more stable state.

6. 06

   Electron capture can compete with positron emission in certain isotopes.

7. 07

   Energy levels of the captured electron must be lower than the energy difference between the initial and final states of the nucleus.

8. 08

   Electron capture can lead to the emission of X-rays as the electron vacancy is filled by an outer electron.

9. 09

   Electron capture is more likely in heavier elements due to their larger number of inner-shell electrons.

10. 10

    Electron capture can be detected by observing the emitted neutrinos or X-rays.
