A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

▪ Abstract Recent studies of state-resolved angular distributions show the participation of
reactive scattering resonances in the simplest chemical reaction. This review is intended for …

The H3+ molecular ion plays a fundamental role in interstellar chemistry, as it initiates a
network of chemical reactions that produce many molecules,. In dense interstellar clouds …

Abstract Our Solar System formed∼ 4.6 billion years ago from the collapse of a dense core
inside an interstellar molecular cloud. The subsequent formation of solid bodies took place …

Context. The high degree of deuteration observed in some prestellar cores depends on the
ortho-to-para H 2 ratio through the H $ _3^+ $ fractionation. Aims. We want to constrain the …

We measure the temperature of warm gas at planet-forming radii in the disk around the
classical T Tauri star (CTTS) TW Hya by modeling the H 2 fluorescence observed in Hubble …

The dissociative recombination of an H 3+ ion after it is struck by a low-energy electron is
important for understanding observations of H 3+ in diffuse interstellar clouds. At the same …

This paper presents the first dissociative recombination (DR) measurement of electrons with
rotationally and vibrationally cold H 3+ ions. A dc discharge pinhole supersonic jet source …

This review covers the work of the three decades since the first spectroscopic identification
of the H 3+ molecular ion outside of the laboratory in 1988, in the auroral atmosphere of the …

A major aim of astrochemistry is to explain the nature and abundance of the molecules
observed in the interstellar medium (ISM). Three kinds of activity are involved:(a) the …
