Abstract
We review proposed production mechanisms of Ta-180 during the nucleosynthes is process. In this nucleus, an electromagnetic coupling between the ground state and the 9(-) isomeric state may strongly affect the produced abundan ces. Possible theoretical electromagnetic paths between the ground state an d the isomeric state are discussed in the framework of the two-quasiparticl e-plus-phonon model and the standard axially-symmetric rotor model includin g Coriolis mixing.
