IMB-3实验是一个大型水切伦科夫环成像探测器，其基准质量为3.3 kton。在7.6千万年的暴露期间（{大约}4.6{times}10{sup 33}thinspnucleonthinspyr）观测到935个包含事件。观测到的速率和特征与大气中微子的预期背景一致。核子寿命的下限被设定为各种各样的衰变模式。{版权所有}{ital 1999} {ital美国物理学会}
The IMB-3 experiment was a large water Cherenkov ring imaging detector with a fiducial mass of 3.3 kton. During a 7.6-kton-year exposure ({approximately}4.6{times}10{sup 33}thinspnucleonthinspyr) 935 contained events were observed. The observed rate and characteristics are consistent with the expected backgrounds from atmospheric neutrinos. Lower limits on the nucleon lifetime are set for a wide variety of proposed decay modes. {copyright} {ital 1999} {ital The American Physical Society}
