Photoabsorption spectrum of Be^+

Journal of the Optical Society of America B, 1985
The absorption spectrum of the ion Be+ has been recorded in the vacuum ultraviolet by utilizing the method of two laser-produced plasmas. The photoionization cross sections of the outer electron for transitions of the type 2s–∊p and 2p–∊d have been measured at threshold; the values are σ = (1.5 ± 0.1) × 10−18 cm2 and σ = (2.5 ± 0.5) × 10−18 cm2 ...

On the spectrum of fullerenes

Acta Crystallographica Section A Foundations of Crystallography, 2002
The most symmetrical C50 to C70 fullerenes with minimum numbers of pairs of adjacent pentagonal facets are considered in this paper. Like the well known C60 (35m) and C70 (10m2) fullerenes with no adjacent pentagonal facets, they appear to be stable in physical experiments and cause the visible peaks in mass spectra of carbon clusters produced by laser

The Spectrum of Syncope

The Journal of Clinical Pharmacology, 1994
Syncope is a loss of consciousness and postural tone. Although arising suddenly from prolonged recumbency or returning from weightlessness to Earth's gravity can result in syncope from orthostatic or vasovagal effects, there are many other possible causes. These causes can he divided into several groups.

Spectrum and Pseudo-Spectrum

2019
In this book all Hilbert spaces will be assumed to separable for simplicity. In this section we review some basic definitions and properties; we refer to Kato (Perturbation theory for linear operators, Die Grundlehren der mathematischen Wissenschaften, Band 132. Springer, New York, 1966), Reed and Simon (Methods of modern mathematical physics.
