Naturally occurring xenon (54Xe) consists of seven stable isotopes and two very long-lived isotopes. Double electron capture has been observed in Xe (half-life 1.8 ± 0.5(stat) ± 0.1(sys) ×10 years) and double beta decay in Xe (half-life 2.165 ± 0.016(stat) ± 0.059(sys) ×10 years), which are among the longest measured half-lives of all nuclides. The isotopes Xe and Xe are also predicted to undergo double beta decay, but this has never been observed in these isotopes, so they are … WebFeb 8, 2016 · This jicama citrus salad from the Yucatan is known as “Xec” or “Xe’ec”, which comes from the Mayan word for “Ensalada” (salad).
