11. Is this equation supposed to represent electron capture ? 12. Electron capture should not increase the atomic mass.13. But when it does, the electrons and nucleons react, in electron capture . 14. This involves electron capture or positron decay of potassium-40 to argon-40. 15. It occurs simultaneously with double electron capture , their branching ratio depending on nuclear properties. 16. The primary decay mode before the most abundant stable isotope 51 V is electron capture . 17. Atomic radioactive decay pathways, most commonly alpha decay, beta decay, or electron capture . 18. He is also known for electron capture dissociation, a method of fragmenting gas phase ions. 19. When a stellar core collapses, the pressure causes electrons and protons to fuse by electron capture . 20. Anomalies in elemental distributions are thought to be partly a result of this effect on electron capture .
