摘要：

We numerically investigate multiphoton ionization of excited hydrogen atoms in magnetic and microwave fields when up to N-I=600 photons are required for ionization. The analytical estimates for the quantum localization length in the classically chaotic regime are in agreement with numerical data. The excitation is much stronger than the case with microwave field only due to the chaotic structure of eigenstates in a magnetic field.
