Potassium Isotopic Compositions of Enstatite Meteorites [PDF]
, 2020 Enstatite chondrites and aubrites are meteorites that show the closest similarities to the Earth in many isotope systems that undergo mass-independent and mass-dependent isotope fractionations. Due to the analytical challenges to obtain high-precision K isotopic compositions in the past, potential differences in K isotopic compositions between ...

Modelling of mercury isotope separation in CP stellar atmospheres: results and problems [PDF]
New Astron.Rev.53:240-245,2009, 2009 Formation of anomalous isotope abundances in the atmospheres of chemically peculiar (CP) stars can be explained by light-induced drift (LID). This effect is additional to the radiative acceleration and appears due to systematic asymmetry of radiative flux in partly overlapping isotopic spectral line profiles.

Radionuclide generator-based production of therapeutic 177Lu from its long-lived isomer 177mLu
EJNMMI Radiopharmacy and Chemistry, 2019 Background In this work, a lutetium-177 (177Lu) production method based on the separation of nuclear isomers, 177mLu & 177Lu, is reported. The 177mLu-177Lu separation is performed by combining the use of DOTA & DOTA-labelled peptide (DOTATATE) and liquid-

Resonant photonuclear isotope detection using medium-energy photon beam [PDF]
Physical Review Special Topics - Accelerators and Beams 15, 024701
(2012), 2012 Resonant photonuclear isotope detection (RPID) is a nondestructive detection/assay of nuclear isotopes by measuring gamma rays following photonuclear reaction products. Medium-energy wideband photons of 12-16 MeV are used for the photonuclear reactions and gamma rays characteristic of the reaction products are measured by means of high-sensitivity Ge ...
