We publish three Roadmaps on photonic, electronic and atomic collision physics in order to
celebrate the 60th anniversary of the ICPEAC conference. In Roadmap II we focus on …

This paper presents a novel reaction microscope designed for ion–atom collision
investigations, established at the Institute of Modern Physics, Chinese Academy of Sciences …

Two-dimensional electron density map (2D map) of binding energy and relative azimuthal
angle (ie, momentum) for the outer-valence molecular orbitals of SF6 has been measured by …

Bond oscillation, a phenomenon characteristic of the molecular electron-density distribution
in momentum space, is demonstrated for the 1 σ g molecular orbital of H 2 with an (e, 2 e) …

Phases of quantum transition amplitudes contain very important information about physical
processes. However, as a rule, they may not be accessed experimentally. This is, in …

An accurate description of electron momentum spectroscopy (EMS) for molecular targets
remains unresolved since its advent several decades ago. Here, we report a multicenter …

We present an analytical model based on the time-dependent WKB approximation to
reproduce the photoionization spectra of an H 2 molecule in the autoionization region. We …

The vibrational and distorted-wave effects are usually invoked to explain the measured
electron momentum profiles for molecular orbitals. The vibrational effect can be accounted …

The binding energy spectra and electron momentum distributions for the outer-valence
molecular orbitals of gaseous cyclopropylamine (CPA) have been measured by (e, 2e) …

Electron momentum spectroscopy is a unique tool for imaging orbital-specific electron
density of molecule in momentum space. However, the molecular geometry information is …
