The research progresses on the investigations of atomic structure and collision dynamics with highly charged ions based on the heavy ion storage rings and electron ion beam traps in recent 20 years are reviewed. The structure part covers test of quantum electrodynamics and electron correlation in strong Coulomb field studied through dielectronic recombination spectroscopy and VUV/x-ray spectroscopy. The collision dynamics part includes charge exchange dynamics in ion-atom collisions mainly in Bohr velocity region, ion induced fragmentation mechanisms of molecules, hydrogen-bound and van de Waals bound clusters, interference and phase information observed in ion-atom/molecule collisions. With this achievements, two aspects of theoretical studies related to low energy and relativistic energy collisions are presented. The applications of data relevant to key atomic processes like dielectronic recombination and charge exchanges involving highly charged ions are discussed. At end of this review, some future prospects of research related to highly charged ions are proposed.

“…Another aspect that motivates the present work stems from the currently growing interest in laser-assisted ion-, electron-, and positron-atom scattering [44][45][46][47][48][49][50]. With the fast development of laser technologies, intense laser fields have become a powerful tool to control and manipulate scattering processes.…”

We investigate the quantum dynamics of target excitation and positronium formation in the positron-hydrogen atom scattering without and with an external assisting laser ﬁeld within a reduced-dimensionality quantum model. Strong interference fringes between the incident and reﬂected positron wave packets are observed in the reaction region. We further investigate the critical behavior of transition probabilities near the channel-opening thresholds for hydrogen excitation and positronium formation, and ﬁnd a strong competition between channels with similar threshold energies but diﬀerent parities. The transmission ratios of the incident positron in diﬀerent reaction channels are calculated and it is shown that only positronium formation in the ground state prefers forward scattering. Our simulation of the positron-hydrogen scattering with an assisting laser ﬁeld indicates that the three-particle bound states can be formed during the collisions due to the photon emission induced by the external laser ﬁeld.
