Existence of long-lived isotopes of a superheavy element in natural Au [PDF]
, 2007 Evidence for the existence of long-lived isotopes with atomic mass numbers 261 and 265 and abundance of (1-10)x10$^{-10}$ relative to Au has been found in a study of natural Au using an inductively coupled plasma - sector field mass spectrometer.

Absolute isotope ratios defining isotope scales used in isotope ratio mass spectrometers and optical isotope instruments [PDF]
Rapid Communications in Mass Spectrometry, 2020 Rationale The isotope delta is calculated from the isotope ratio of a sample and the absolute isotope ratio of the zero reference point defining each stable isotope international scale ( R std ). Therefore,

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-

ISOTOPIC CONVERGENCE THEOREM [PDF]
Journal of Knot Theory and Its Ramifications, 2013 When approximating a space curve, it is natural to consider whether the knot type of the original curve is preserved in the approximant. This preservation is of strong contemporary interest in computer graphics and visualization. We establish a criterion to preserve knot type under approximation that relies upon pointwise convergence and convergence in

The influence of intruder states in even-even Po isotopes [PDF]
, 2015 We study the role of intruder states and shape coexistence in the even-even $^{190-206}$Po isotopes, through an interacting boson model with configuration mixing calculation. We analyzed the results in the light of known systematics on various observable
