متن کاملAtomic mass of Li using a Penning-ion-trap mass spectrometer
The atomic mass of Li has been measured using a Penning-ion-trap mass spectrometer to be 6.015 122 795~16! u. The fractional measurement uncertainty of 62.7310 represents a 30-fold improvement over that of the accepted published value. External ion sources were used to create ions outside the cryogenic ~4 K! environment of the Penning trap and an ion-transport beamline was used to deliver ions ...
متن کاملA quadrupole mass spectrometer for resolution of low mass isotopes.
The qualitative and quantitative identification of low mass isotopes in the mass range 1-6 u poses certain difficulties when attempting to achieve the required resolution with an instrument suitable for deployment within a process environment. Certain adjacent species present in the process sample (HT and D(2)) require a resolution greater than 930 to achieve an accurate measurement. We demonst...
متن کاملDiscovery of the astatine, radon, francium, and radium isotopes
Currently, thirty-nine astatine, thirty-nine radon,??? isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented. ∗Corresponding author. Email address: [email protected] (M. Thoennessen) Preprint submitted to Atomic Data and Nuclear ...
متن کاملEUROPEAN ORGANISATION FOR NUCLEAR RESEARCH Ramsey Technique Applied in a Penning Trap Mass Spectrometer
The Ramsey method has been applied in an experiment aiming for accurate mass determination of unstable isotopes. The ion motion in a Penning trap has been excited with time-separated oscillatory elds and Ramsey fringes were observed in the case of dipole and quadrupole excitation. The experimental resonances are in good agreement with theory. Further applications of the technique are discussed....
