High-Precision Mass Measurements of Radionuclides with Penning Traps
- Physics, Environmental Science
The mass of an atom is directly related to the binding energy of all its constituents. Thus, it provides information about all the interactions inside the atom. High-precision mass measurements hence…
Direct mass measurements above uranium bridge the gap to the island of stability
Direct mass measurements of trans-uranium nuclides, located at the farthest tip of the actinide species on the proton number–neutron number diagram, represent the gateway to the predicted island of stability and advance direct mass measurements by ten atomic numbers with no loss in accuracy.
Nuclear applications of inorganic mass spectrometry
There are several basic characteristics of mass spectrometry that are not always fully appreciated by the science community. These characteristics include the distinction between relative and…
The role of mass spectrometry in atomic weight determinations
The 1914 Nobel Prize for Chemistry was awarded to Theodore Richards, whose work provided an insight into the history of the birth and evolution of matter as embedded in the atomic weights. However,…
Masses of exotic calcium isotopes pin down nuclear forces
The mass determination of the exotic calcium isotopes 53Ca and 54Ca is reported, using the multi-reflection time-of-flight mass spectrometer of ISOLTRAP at CERN, to establish a prominent shell closure at neutron number N = 32, in excellent agreement with the theoretical calculations.
Q value related mass determinations using a Penning trap
We report here about measurements of reaction and decay Q values by precise determination of pairs of atomic masses. These were performed with the Penning trap mass spectrometer SMILETRAP.…

Masses of stable xenon isotopes: Check for internal consistency via ion cyclotron resonance mass spectrometry.
- PhysicsPhysical review. C, Nuclear physics
A Fourier transform ion cyclotron resonance (ICR) mass spectrometer has been used to measure the relative masses of five of the stable isotopes of xenon, comparable to that of the reference mass values.
Mass Spectroscopy Second Edition
In this book the authors describe the principles of mass spectrometry and the uses to which mass spectrometers have been put. The text opens with a brief account of early instruments and this is…
