Atomic versus molecular Auger decay in CH2Cl2 and CD2Cl2 molecules.
A. C. F. Santos,D. N. Vasconcelos,M A MacDonald,M. M. Sant’Anna,Bruno Nunes Cabral Tenorio,Alexandre B. Rocha,V. Morcelle,Narayana Appathurai,Lucia Zuin +8 more
TL;DR: To support the presence of the ultrafast dissociation mechanism in the dichloromethane molecule, a series of high-level ab initio quantum mechanical calculations were performed at multiconfigurational self-consistent field (MCSCF) and multireference configuration interaction (MRCI) levels of theory.

Ultrafast molecular dynamics of dissociative ionization in OCS probed by soft X-ray synchrotron radiation
Ali Ramadhan,Benji Wales,Isabelle Gauthier,Reza Karimi,M A MacDonald,Lucia Zuin,Joseph Sanderson +6 more
TL;DR: In this paper, soft X-rays from the 3rd generation Canadian Light Source have been used in conjunction with a multi coincidence time and position sensitive detection apparatus to observe the dissociative ionization of OCS.

Photoelectron and threshold photoelectron valence spectra of pyridine
Małgorzata A. Śmiałek,Małgorzata A. Śmiałek,M A MacDonald,Sylwia Ptasinska,Lucia Zuin,Nigel J. Mason +5 more
TL;DR: In this paper, the pyridine molecule has been examined by the means of photoelectron and threshold photo-electron spectroscopies and the ionization energies for both outer and inner valence orbitals and new adiabatic values were also resolved.

TL;DR: In this paper, the polarization changes simultaneously occurring with intensity changes due to carbon contamination of optical components at two plane grating beam lines PGM-1 and PGM2 at BESSY II.

An angle-resolved dissociative photoionization study of the c4Σ−u state in O+2 using the TPEPICO technique
TL;DR: In this article, the TPEPICO technique was used to measure the coincidence yield between threshold photoelectrons and photoions, and the authors obtained τ1 = 6.0 ± 0.05, which is significantly at variance with the predicted value of 1.6.
