摘要：

By using path integral methods we derive the equation for large amplitude collective motion for a schematic two-level model. The original fermion theory is reformulated in terms of a collective (Bose) field. The classical equation of motion for the collective field coincides with the time-dependent Hartree equation. Its classical solution is quantized by means of the field-theoretical generalization of the WKB method. This yields the exact excitation energies. © 1979.
