Abstract : The effects of the distribution of nuclear magnetization on hyperfine structure (Bohr - Weisskopf effect) are studied in the case of mu-mesic atoms. The configuration mixing model os nucleus is used for the calculation and it is shown that the reduction of hyperfine structure is of order 15% for Al-27 and of order 50% for Bi-209. Calculations are also made in the framework of the collective model again for Al-27 and also for Ta-181. The vacuum polarization effects on hyperfine structure are also studied and are found to be of order 1% for light nuclei. (Author)
