Abstract：
Based on the variational method and using two classes (exponential and square) nuclear charge distributions and two classes (Gaussian and exponential) trial wave functions the 1s and 2p energy levels of muonic atoms are calculated and compared with the accurate calculation ^[1]. Then we use the LCAO (Linear Combination of Atomic Orbitals) to calculate the foure energy levels of Muon in the two centre nuclear extended coulombian potential, and use the PSS (Purterbation of Stationary States) to solve the time-dependent Schrödinger equation and obtain the final Muon probabilities for these four states. We find that after the prompt fission of Muonic atom. Muon is mainly attached on the 1s state of the heavy fragment, only 3.8—5.1% of the probabilities are attached on 1s state of the light fragment, and 0.7—0.9% and ~0.1% on the 2p states of the heavy fragment and the light fragment respectively. These results are in agreement with those of references [2], [3], and also in accordance with the experimental results within the experimental errors.
