Electron capture is a process in which an atom captures an electron and modifies its atomic structure. Some synonyms for electron capture include inverse beta decay, K-capture, K-electron capture, and orbital electron capture. These terms refer to the same process of capturing an electron by an atom. The result of the electron capture process depends on the atomic number of the atom and the energy levels of the electrons involved. This process is often used in nuclear physics and medical imaging to produce gamma rays, which can be used to create images of internal structures. Understanding electron capture and its synonyms is important for scientists and researchers working in the fields of physics and medicine.
