We carried out a new attempt to check for the presence promethium lines in
the spectrum of HD101065 (Przybylski's star). The neutron capture element
promethium does not have stable isotopes and the maximum half-life time is
about 18 years. Thus its presence in this peculiar star would indicate an
ongoing process of irradiation of its surface layers with free neutrons.
Unfortunately, almost all promethium lines are heavily blended with lines of
other neutron capture elements and other species. We selected and analysed
three lines of promethium (Pm I and Pm II) and came to the conclusion that at
present it is impossible to definitely claim the presence of this element in
Przybylski's star atmosphere.Comment: Accepted for publication in Astronomische Nachrichte
