We develop a numerical method to study particle decay process of pp\mu*_{J\nu} muonic molecules. This muonic molecular ion is formed in collisions of excited p\mu (2s) atoms with 2 H molecules. At before, we applied wave functions where were not exact. The present method is used to calculate the decay widths with an improved variational wave function. The calculations are based on Hamiltonian that includes the Coulomb interactions only, and give reasonable energy levels and particle decay widths for the meta-stable pp\mu*_{J\nu} molecular ion. Here, the wave function of this three-body is introduced.
