The discovery of carbon fullerene cages and their solids opened a new avenue to build
materials from stable cage clusters as “artificial atoms” or “superatoms” instead of atoms …

The energy difference between an uncharged species and its negative ion, referred to as an
electron affinity (EA), is an important property of atoms and molecules. Negative ions, or …

Proudly serving the scientific community for over a century, this 97th edition of the CRC
Handbook of Chemistry and Physics is an update of a classic reference, mirroring the growth …

Anion photoelectron spectroscopy (PES) has become one of the most versatile techniques
in chemical physics. This article briefly reviews the history of anion PES and some of its …

Ion thermochemistry is of great practical importance to mass spectrometry. Ion source
intensities and fragmentation patterns in mass spectra are intimately related to ion …

The geometrical and electronic structures of the germanium clusters with up to 25 atoms are
studied by using density-functional theory with the generalized gradient approximation. The …

Slow photoelectron velocity-map imaging spectroscopy of cryogenically cooled anions (cryo-
SEVI) is a powerful technique for elucidating the vibrational and electronic structure of …

We have performed a systematic ground state geometry search for Ge n neutrals and
cations in the n≤ 16 size range using density functional theory–local density approximation …

The extremely improved resolution of ZEKE spectroscopy is one of its main advantages over
conventional photoelectron (PE) spectroscopy. A good illustration of this is provided by the …

Investigations on germanium clusters in the neutral, anionic, and dianion states Ge nx (n=
2− 12 and x= 0,− 1,− 2) are performed using quantum chemical calculations with the B3LYP …
