Abstract
We present results for levels in K (the mirror of nucleus Ar) that are used in reaction rate calculations. The levels are also determined from the isobaric mass multiplet equation and the binding energies of the analog states as a check on the assignment of spins and parity. Where the analog states are not known, the levels are calculated with two-body interactions that use the -shell interactions USDA and USDB as the charge-independent parts, with a Coulomb, charge-dependent, and charge-asymmetric Hamiltonian added. The -decay lifetimes and Al to K spectroscopic factors are calculated with the same interactions, and together with experimental information on the levels of excited states, are used to determine the Ar()K reaction rates.
