Coherence Time Effects on J/psi Production and Suppression in Relativistic Heavy Ion Collisions [PDF]
, 1999 Using a coherence time extracted from high precision proton-nucleus Drell-Yan measurements and a nuclear absorption cross section extracted from pA charmonium production experiments, we study J/psi production and absorption in nucleus-nucleus collisions.

Electron Microprobe Chemical Dating of Uraninite as a Reconnaissance Tool for Leucogranite Geochronology [PDF]
, 2007 We suggest that electron microprobe techniques may be employed to date Tertiary samples of uraninite (UO~2~), which can contain very high concentrations of radiogenic Pb after only a few million of years of U and Th decay. Although uraninite is regarded

The End Of Nucleosynthesis: Production Of Lead And Thorium In The Early Galaxy [PDF]
, 2009 We examine the Pb and Th abundances in 27 metal-poor stars (-3.1 56) enrichment was produced only by the rapid (r-) nucleosynthesis process. New abundances are derived from Hubble Space Telescope/Space Telescope Imaging Spectrograph, Keck/High ...

, 1998 Motivated by the recent experimental evidence of commensurate surface CDW in Pb/Ge(111) and Sn/Ge(111) $\sqrt{3}$-adlayer structures, as well as by the insulating states found on K/Si(111):B and SiC(0001), we have investigated the role of electron ...

Возраст и тектоническая позиция плагиогранитоидов Саракокшинского массива (Горный Алтай)
Литосфера, 2019 Результаты изучения структурно-геологического положения, вещественного состава, геохронологических (U-Pb) и изотопно-геохимических (Sm-Nd) исследований плагиогранитоидов Cаракокшинского габбро-диорит-тоналит-плагиогранитного массива (северо-восточная ...

Extensional faulting on Tinos island, Aegean sea, Greece: How many detachments? [PDF]
, 2007 Zircon and apatite fission track (ZFT and AFT) and (U-Th)/He, 40Ar/39Ar hornblende, and U-Pb zircon ages from the granites of Tinos Island in the Aegean Sea, Greece, suggest, together with published ZFT data, that there are three extensional detachments ...
