%X Based on the Born-Oppenheimer approximation,the zero-temperature dynamics of the two-state system is studied in this paper. Treating the bath as bosons,the transition probability iS givenand discussed for various spectral distribution of the reservoir. As a result of computer siinulation,thetransition probability displays a .damped oscillation function of time, when the spectral distrubutiontakes so-called the Ohmic form with a cut-off mp,whereas the quantum jump appears in the transitionprobability when the spectral distribution is random with the same cut - off. For the purpose ofcomparison, the temporal properties of the probability is also derived and discussed for the case inwhich the bath is treated as infinite 0scillators.
