Dark Matter Detector Observes Rarest Event Ever Recorded

[Buzz Bloom]

TL;DR

The achievement is the first time scientists have measured the half-life (the amount of time it takes to lose half its radioactivity) of this xenon isotope based on a direct observation of its radioactive decay.

The URL below is from Rensselaer Alumni Magazine. It is about an unexpected observation of an xenon atom decay using the equipment designed for detecting dark matter particle interactions with xenon.

Hi Orodruin:

I promise I will try to do it better next time.

Thanks for posting the arxiv link.

BTW: I found another Nature source which has a lot more information than the Nature paper abstract.
