Abstract

Models of astronomical phenomena require a number of nuclear physics inputs to characterize the contribution of these events to the production of the observed elements. Masses and the excitation energy levels, spins, and partial and total decay widths of states are particularly important. Reported here are the mass measurements of 22Mg and 26Si which are required to understand the contribution of novae to the observed (or unobserved) galactic abundances of 26Al and 22Na. A description of the Canadian Penning trap mass spectrometer and Yale spectrograph which were used to determine these masses is presented and is followed by a brief description of the astrophysical consequences. © Copyright owned by the author(s).
