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.
In Seeing Like a Citizen, Kara Moskowitz approaches Kenya’s late colonial and early postcolonial eras as a single period of political, economic, and social transition. In focusing on rural Kenyans—the vast majority of the populace and the main targets of development interventions—as they actively sought access to aid, she offers new insights into the texture of political life in decolonizing Kenya and the early postcolonial world. Using multisited archival sources and oral histories focused on the western Rift Valley, Seeing Like a Citizen makes three fundamental contributions to our understanding of African and Kenyan history. First, it challenges the widely accepted idea of the gatekeeper state, revealing that state control remained limited and that the postcolonial state was an internally varied and often dissonant institution. Second, it transforms our understanding of postcolonial citizenship, showing that its balance of rights and duties was neither claimed nor imposed, but negotiated and differentiated. Third, it reorients Kenyan historiography away from central Kenya and elite postcolonial politics. The result is a powerful investigation of experiences of independence, of the meaning and form of development, and of how global political practices were composed and recomposed on the ground in local settings.
