Giant Coulomb broadening and Raman lasing on ionic transitions
, 1996 CW generation of anti-Stokes Raman laser on a number of blue-green argon-ion lines (4p-4s, 4p-3d) has been demonstrated with optical pumping from metastable levels 3d'^2G, 3d^4F.

, 1996 It is shown that polarizable neutral systems can drift in crossed magnetic and electric fileds. The drift velocity is perpendicular to both fields, but contrary to the drif t velocity of a charged particle, it exists only, if fields vary in space or in ...

An Atom Laser Based on Raman Transitions
, 1997 In this paper we present an atom laser scheme using a Raman transition for the output coupling of atoms. A beam of thermal atoms (bosons) in a metastable atomic state $|1 >$ are pumped into a multimode atomic cavity.

Atomic Data for Permitted Resonance Lines of Atoms and Ions from H to Si, and S, Ar, Ca and Fe
, 1996 We list vacuum wavelengths, energy levels, statistical weights, transition probabilities and oscillator strengths for permitted resonance spectral lines of all ions of 18 astrophysically important elements (H through Si, S, Ar, Ca, Fe).

Atom-by-Atom Determination of Deuterium Atom Distribution in the Surface by Atom Probe.
SHINKU, 1998 Hydrogen is a major residual gas constituent in extremely high vacuum (XHV) and its outgassing behavior has been suggested to be closely related to its concentration and distribution in the surface layers of materials used to fabricate vacuum chambers.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

Towards to the mind-body problem
Journal of Education, Health and Sport, 2021 The mind-body problem is one of the most difficult challenges of modern science. An interesting attempt at providing a reductionist model of reality was made in the 18th century by Ruder Josip Bošković. The attractiveness of this model lies in the

Nuclear spin--rotation interaction in the hydrogen molecular ion
, 1995 The nuclear spin--rotation interaction in the hyperfine structure of the hydrogen molecular ion is investigated. The interaction constants are determined and are found to differ in sign and magnitude compared to another theory, but they are in agreement ...
