Title Laser Assisted Nuclear Decay Spectroscopy : A New Method for Studying Neutron-Deficient Francium Isotopes Author(s) Lynch, Kara Marie Publication Cham, Springer International Publishing, 2015. Description XIII, 131 p. 95 illus., 46 illus. in color : online resource Abstract Note This work details an application of collinear resonance ionization spectroscopy for the separation of short-lived isomeric states and their subsequent study with decay spectroscopy.??It reports the successful construction of??a novel decay spectroscopy apparatus that can operate at pressures below 1 x 10^-9 mbar.??The method is demonstrated by separating the nuclear ground and isomeric states of 204Fr and performing alpha-decay spectroscopy. An equivalent mass spectrometer would require 4.6 million times as much resolution to achieve the same result. This work unambiguously confirms the existence of a second isomeric state in 204Fr. The author also demonstrates the effectiveness of this method for laser spectroscopy and identification of hyperfine-structure components with energy tagging. This method was successfully used in 202Fr to identify ground and isomeric states. The measurement of 202Fr reported in this thesis demonstrates a factor of 100 improvement in sensitivity compared to state-of-the-art fluorescence techniques.??The work reported in this thesis won the author the IOP Nuclear Physics Group Early Career Prize ISBN,Price 9783319071121 Keyword(s) 1.
