Thehigh-order harmonic generation (HHG) by local field enhancement is investigated using two-centermolecule H2+ with fixed nuclear separation,which is initially
The photoionization cross sections of Ti2+ in the ground state ([Ne]3s23p63d23Fe)are calculated using both nonrelativistic (LS-coupling) and relativistic (Breit
Energy levels,radiative and Auger transition rates of the ls2s22p2,ls2s2p3,and ls2p42,4L (L =S,P,D) resonances in the boron isoelectronic sequence are calculate
