The chemistry of deuterium, as well as that of hydrogen and helium, in the
postrecombination era of the expanding early universe is presented. A thorough survey of all …

carried out of the abundances of Li, Li~ Li, LiH, and LiH~ as a function of redshift z for
several cosmological models. Atomic lithium is found to recombine at a redshift of about 450 …

We present models of the low and high solar activity thermospheres and ionospheres of
Venus for a background atmosphere based largely on the VTS3 model of Hedin et al.[1983] …

This paper summarizes the most recent knowledge concerning normal and three-body
association ion-molecule reactions between small hydrocarbon ions (C m H $\mathstrut …

Alkaline earth monoalkoxide free radicals (MORs) have molecular properties conducive to
direct laser cooling to sub-millikelvin temperatures. Using dispersed laser induced …

Threshold photoelectron spectra (TPES) of the isotopomers of the methyl radical (CH3,
CH2D, CHD2, and CD3) have been recorded in the 9.5− 10.5 eV VUV photon energy range …

Aims. We present an experimental investigation of the exothermic reactions of NH+,, and
ions with H 2 at temperatures relevant for interstellar clouds. Methods. The reactions were …

Jacket illustration. CryoSEM micrograph of a freeze-fractured yeast cell. Specimen was
prepared according to Walther et al (1995) and imaged using back-scattered electrons …

The Active Thermochemical Tables (ATcT) yield 8.477±0.007 eV as the ionization energy of
the vinyl radical, which agrees with wave function theory results. The photoionization …

Time-dependent quantum wave packet dynamics study is carried out to investigate the initial
state selected channel specific reactivity of H+ LiH collisional system on a new and more …
