Scott Carmichael successfully defended his Ph.D. thesis on April 2, 2025 entitled "An experimentally constrained reaction rate for ⁵⁷Ni(p,γ)⁵⁸Cu" advised by Prof. Dan Bardayan. Scott's thesis involved three distinct but highly correlated projects. The primary goal was to constrain the amount of observable ⁴⁴Ti produced in supernovae by understanding the ⁵⁷Ni(p,γ)⁵⁸Cu reaction rate that had never previously been experimentally constrained. Scott proposed a PAC-accepted experiment at Argonne using a unique detector combination including the highly-demanded GRETINA and ORRUBA detector arrays. This first high-resolution study of ⁵⁸Cu resulted in a significantly improved understanding of ⁵⁸Cu levels. Scott then led the installation and commissioning of the multi-million dollar Enge spectrometer at the NSL, which resulted in further constraints on the ⁵⁷Ni(p,γ)⁵⁸Cu reaction. Finally Scott worked closely with Prof. Rebecca Surman on nucleosynthesis calculations showing the dramatic reduction in uncertainties related to ⁴⁴Ti nucleosynthesis as a result of his work. The combination of these unique and world-leading approaches impacting our understanding of ⁴⁴Ti production is of wide interest, and Scott will submit the results to Physical Review Letters.
