Three-Body Nonmesonic Weak Decay of the CΛ12 Hypernucleus

Phys. Rev. Lett. 103, 182502 – Published 30 October 2009


We have measured the branching ratio of the three-body process in the nonmesonic weak decay of CΛ12 to be 0.29±0.13. This result was obtained by reproducing the nucleon and the nucleon pair yields introducing a measured final state interaction. At the same time, we have determined the absolute decay widths, Γn and Γp, along with Γ2N, whose relative ratio has been a long-standing puzzle. Including the three-body process, we have successfully reproduced the nucleon energy distribution, the coincidence two-nucleon angular correlation, and the momentum sum distribution simultaneously.
