TL;DR: It is found that the parity of the vibrational Hermite polynomials influences not just the amplitude, but also the phase of the transition matrix elements, and the latter is sufficient, even in the absence of resonant enhancements, to account for enhanced vibrational dependencies in the chiral photoionization dynamics.

TL;DR: Photoionization of the chiral monoterpene limonene has been investigated using polarized synchrotron radiation between the adiabatic ionization threshold, 8.505 and 23.5 eV, and a rich vibrational structure is seen in the threshold photoelectron spectrum and is interpreted using a variety of computational methods.

TL;DR: The valence-shell ionization spectrum of bromobenzene was studied using the non-Dyson third-order algebraic-diagrammatic construction [nD-ADC(3)] approximation for the electron propagator to reveal a whole class of low-lying low-intensity two-hole-one-particle (2h-1p) doublet and quartet states, which are relevant to various photoionization processes.

TL;DR: In this article, the position of a particle incident on a microchannel plate detector was encoded in less than 1 mu s. This allowed operation in a pulse-counting mode at high count-rates with minimal losses due to paralysis, while maintaining high spatial resolution.
