A microscopic description of the alpha decay of the odd mass nuclei will be presented for axially deformed nuclei. Realistic mean field + pairing residual interaction in a very large single particle basis has been used. Systematics for At and Rn isotopes, as well as for221Fr,241Am and Pa ‐ isotopes. It is found that the approach gives predictions in good agreement with experimental data for well deformed nuclei. New recent calculations for241–243Am,253–255Es and255–257Fm isotopes will be discussed. © 2003 American Institute of Physics
