We demonstrate that the isotope shift in isotopomers of diatomic molecules, where the
nucleus of one of its constituent atoms is replaced by another isotope, can be expressed as …

Long-lived isotopes of plutonium were studied using two complementary techniques, high-
resolution resonance ionization spectroscopy (HR-RIS) and collinear laser spectroscopy …

Filament-based dispensers of thorium have been investigated at the IGISOL facility,
Jyväskylä, for potential use as a thorium ion source for future collinear laser spectroscopy …

Abstract Using the sensitive Radiation Detected Resonance Ionization Spectroscopy
(RADRIS) technique an optical transition in neutral nobelium (No, Z= 102) was identified. A …
