摘 要：The photodetachment dynamics of Hion in a harmonic potential plus an oscillating electric field has been studied using the time-dependent closed orbit *** analytical formula for calculating the photodetachment cross section of this system has been put *** is found that thephotodetachment cross section of this system is nearly unaffected for the weak oscillating electric field strength,but oscillates complicatedly when the oscillating electric field strength gets *** addition,the frequency of the harmonic potential and the oscillating electric field can also affect the photodetachment dynamics of this *** the increase of the frequency in the harmonic potential and the oscillating electric field,the number of the closed orbit for the detached electron is increased,which makes the oscillatory structure in the photodetachment cross section become much more *** research provides an intuitive understanding for the photodetachment dynamics driven by a harmonic potential plus an oscillating electric field from a space and time dependent *** study is very useful in guiding the future experimental research for the photodetachment dynamics in the electric field both changing with space and time.
