Internal conversion coefficients (ICC's) have been calculated for protactinium and transition energies between 170 eV and 10 keV. The ICC's for [ital E]1 multipolarity show an unusual behavior, which cannot be approximated by an exponential dependence on the transition energy, whereas the ICC's for [ital M]1 and [ital E]2 multipolarities closely follow such a dependence. Using the newly calculated ICC's the unusually strong enhancement'' of a possible 220 eV [ital E]1 transition in [sup 229]Pa proposed earlier is reduced by a factor of [similar to]5, yielding an induced electric dipole moment similar to that observed in the neighboring octupole-deformed isotopes.
