Reportedly, an extreme rare particle physics occasion has been observed by scientists with the help of a detector, which is chasing for dark matter that is the mysterious material, which physicists have yet to perceive. According to scientists along with the XENON Collaboration said that, the radioactive decay of a substance called xenon-124, xenon’s isotope had been observed by them, which is an odorless and colorless noble gas found in minute quantities in the atmosphere. Scientists have been eluded for decades by the event named a “2-neutrino double electron arrest”.
The research was recently published in the Nature journal. Ethan Brown, co-author of the study and a professor of physics said that, this event is occurred when 2 protons present inside a nucleus are converted simultaneously into neurons by the preoccupation of 2 electrons from one of the nuclear shells and the release of 2 electron neutrinos. After this, a predictable cascade is shoot out by the event, of Auger electrons and X-rays, looked by scientists using an ultra-sensitive sensor, buried nearly five-thousand feet underneath Gran Sasso mountain of Italy where it is protected from cosmic emissions.
Ethan Brown told Newsweek that, it has been shown by us that the rarest events ever recorded can be observed by us. An isotope previously thought to be totally steady has now been exposed to deterioration on an unbelievably extended timescale is the key finding. Half-life of xenon-124 has been estimated by the team and that is found to be eighteen sextillion years, which is 18,000,000,000,000,000,000,000 years that 1 trillion more than the age of our universe, rendering to team. It was written by the team in a statement that it is the lowest process that has ever been measured directly. Brown told that, this is really amazing to witness this event, this oddest thing ever verified can be measured by our detector.
