The History of Nuclidic Masses and of their Evaluation [PDF]
Int.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]
Journal 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]
arXiv, 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 ...
