Our exact theory for continuous harmonic perturbation of a one dimensionalmodel atom by parametric variations of its potential is generalized for thecases when a) the atom is exposed to short pulses of an external harmonicelectric field and b) the forcing is represented by short bursts of differentshape changing the strength of the binding potential. This work is motivatednot only by the wide use of laser pulses for atomic ionization, but also by ourearlier study of the same model which successfully described the ionizationdynamics in all orders, i.e. the multi-photon processes, though being treatedby the non-relativistic Schr\"odinger equation. In particular, it was shownthat the bound atom cannot survive the excitation of its potential caused byany non-zero frequency and amplitude of the continuous harmonic forcing. Ourpresent analysis found important laws of the atomic ionization by short pulses,in particular the efficiency of ionizing this model system and presumably realones as well.
