11. 2f-Wavelength Modulation-Diode Laser Absorption Spectroscopy of Rb
Sammanfattning : .... LÄS MER
12. The Penning trap mass spectrometer SMILETRAP II and evaporative cooling of highly-charged ions
Sammanfattning : Accurate mass values have wide-ranging applications in physics and metrology, allowing, for example, to test quantum electrodynamics and fundamental symmetries, to determine fundamental constants, and to establish weight standards. This thesis describes the new high-precision double-Penning trap mass spectrometer SMILETRAP II which aims at relative uncertainties in the mass determination of 10-10 and below. LÄS MER
13. Nuclear structure aspects of proton and alpha particle decay
Sammanfattning : .... LÄS MER
14. Mössbauer studies with semiempirical interpretations of iron-complexes
Sammanfattning : .... LÄS MER
15. New atomic masses related to fundamental physics measured with SMILETRAP
Sammanfattning : This thesis describes the recent improvements of the SMILETRAP Penning trap mass spectrometer and a number of interesting high precision mass measurements, which have been performed using the improved apparatus, and are relevant in todays fundamental physics problems. The mass of the hydrogen-like 24,26Mg ions as well as the masses of the hydrogen- and lithium-like 40Ca ions are presented in this work that are indispensable input values when evaluating g-factor measurements of the bound electron.
