The effect of muonic molecules complex ([µd3He]+ J e−) forming with different spin states (J = 0, 1) in various decay channels on the cycling rate, the effective sticking coefficient, and the neutron yield per muon stopped in mixture was studied. It was shown that the error of the relative neutron yield is decreased in the optimum physical condition of the deuterium in the mixture by considering the effect of various decay channels of the muonic molecule complex.
