Abstract
The width of the neutral kaon with respect to its decay to a positively charged kaon, an electron, and an antineutrino is calculated. The branching ratios for the decay of KL and KS mesons to \({K^ + }{e^ - }{\bar \nu _e}\) are found to be about 4 × 10−9 and 10−11 respectively. The calculations presented in this article are also valid for neutral antikaons decaying to a negatively charged kaon, a positron, and a neutrino.
