The History of Nuclidic Masses and of their Evaluation [PDF]

open access: yesInt.J.Mass Spectr.Ion Process. 251 (2006) 85-94, 2006
This paper is centered on some historical aspects of nuclear masses, and their relations to major discoveries. Besides nuclear reactions and decays, the heart of mass measurements lies in mass spectrometry, the early history of which will be reviewed first.

Interferometric mass spectrometry [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2021
Accelerator mass spectrometry (AMS) is a widely-used technique with multiple applications, including geology, molecular biology and archeology. In order to achieve a high dynamic range, AMS requires tandem accelerators and large magnets, which thus confines it to big laboratories.

Nuclear Masses in Astrophysics [PDF]

open access: yesarXiv, 2008
Among all nuclear ground-state properties, atomic masses are highly specific for each particular combination of N and Z and the data obtained apply to a variety of physics topics. One of the most crucial questions to be addressed in mass spectrometry of unstable radionuclides is the one of understanding the processes of element formation in the ...

Optomechanical mass spectrometry [PDF]

open access: yesNature Communications, 2020
AbstractNanomechanical mass spectrometry has proven to be well suited for the analysis of high mass species such as viruses. Still, the use of one-dimensional devices such as vibrating beams forces a trade-off between analysis time and mass resolution.
