本文报道了在EXO-200实验中用223 kg·年辐照量研究束缚在核中的核子的不稳定性。分别为核子衰变到和建立了和的寿命极限。这些是迄今为止最严格的,分别超过了先前的衰变极限的9倍和7倍。
A search for instability of nucleons bound innuclei is reported with 223 kg·yr exposure ofin the EXO-200 experiment. Lifetime limits ofandare established for nucleon decay toand, respectively. These are the most stringent to date, exceeding the prior decay limits by a factor of 9 and 7, respectively.
