Towards quantum state-to-state understanding of ion–molecule
2023年7月20日 · To study ion–molecule scattering dynamics at low collision energies, we constructed a crossed-beam setup based on three-dimensional (3D) velocity-map imaging (VMI), which can simultaneously...
深非弹性分子碰撞中的光散射 - 科学网
2022年3月21日 · We rationalized these findings by extending the textbook model of hard-sphere scattering—taking inelastic energy transfer into account—and attribute the forward scattering to glory-type trajectories caused by attractive forces. This phenomenon, which we refer to as hard-collision glory scattering, is predicted to be ubiquitous.
our theory only forward glory scattering is detected during atomic single ionization, the deviation implies the dominant contribution of the backward rescattering to the high energy electron. Here the wavelength of the laser is 800 nm, and the peak value of the electric field ε 0 is 0.05 a.u..
Glory scattering in deeply inelastic molecular collisions
For deeply inelastic collisions between NO radicals and CO or HD molecules, we observed forward scattering in fully resolved pair-correlated differential cross-sections, despite the low impact parameters that are needed to induce a sufficient energy transfer.
Quantum Interference of Glory Rescattering in Strong-Field …
2018年10月3日 · The characteristic of the Bessel function is determined by the common angular momentum of a number of semiclassical paths termed as glory trajectories, which are launched with different nonzero initial transverse momenta distributed on a specific circle in the momentum plane and finally deflected to the same asymptotic momentum, which is along ...
Glory “in the shadow of the rainbow” - ScienceDirect
1999年3月22日 · We show that the angular distribution of the nuclear scattering amplitude behaves like the zeroth-order Bessel function with a fixed frequency at extremely forward angles even if there exists no genuine forward glory scattering.
Glory scattering in deeply inelastic molecular collisions
2022年3月21日 · This is attributed to ‘hard-collision glory scattering’, a mechanism that appears to be ubiquitous in molecule–molecule collisions. For molecular collisions, the deflection of a molecule’s trajectory provides one of the most sensitive probes of the interaction potential and there are general rules of thumb that relate the direction of ...
