Ionization rates are calculated for differentinitial states. The evolution of electronic wavefunction at fixed inter-nuclear separations are simulated andanalyzed. The results obtained for the ground state of this 1-D model of H2+ show appreciable qualitative agreement with the results obtained previously in the 2-D and 3-D studies. The Ponderomotive energy effect on the beginning of ionization in different initial states is observed. The above threshold ionization has a large contribution in the ionization of electrons, except for the ground state and at equilibrium inter-nuclear separation. The ionization rates show that at some inter-nuclear separations larger than 4.0 au, resonance enhancement ionization by some higher excited states occur. At inter-nuclear separations shorter than 4.0 au, the ground state does not show any resonance with higher excited states.}, keywords = {Intense laser,TDSE,above threshold, ionization rate,H2+,Ponderomotive,wavepacket,1-D model}, url = {https://ijsts.shirazu.ac.ir/article_2205.html}, eprint = {https://ijsts.shirazu.ac.ir/article_2205_ea6a4e3751c0d1a9a07ca411bc9204f0.pdf} }
