Assume you want to find experimental evidence of the proton decay. For this, you use a cylindrical tank with 36 meters high and 17 meters radius which is full of water (18 g / mol). Around the tank are detectors whose overall detection efficiency of a proton decay that gives within the deposit is 20%.Admitting that collaboration has operated the device for an effective period of one year, where the average life than the proton should have for that period had been possible to detect 3 decays?I'm not understanding what they mean with "3 decays"... Like 3 half-lives?
The correct answer is 7.3 x 10^32 years...
