Measurement of the Nuclear Capture Rate of Muons by Free Deuterons

Abstract
We have measured the nuclear capture rate of negative muons by deuterons in μd atoms. The experiment was performed by stopping negative muons in a target of ultrapure gaseous hydrogen at 7.6 atm with 5.2% deuterium and looking at the outgoing neutrons. The result is Λexpt=451±70 sec1.
