The study of the muon spallation products is essential for rate event detection in neutrino detectors, double beta decay experiments, and dark matter searches. In the KamLAND detector, energetic muons interact mainly with 12C in the liquid scintillator and generate neutrons and isotopes by electromagnetic or hadronic processes. The neutron production yield is evaluated to be (2.8 +- 0.3) x 10^-4 n / (mu (g/cm2)). For other isotopes, the production yields are measured from the observed time correlation related to known isotope lifetimes.
