Since there are no known natural nucleosynthesis mechanisms that can
       qualitatively duplicate the   asymptotic  fission  abundances,   the
       predicted observational characteristics   (if  observed)  could  not
       easily be interpreted as a natural phenomenon.  They have suggested

                                      Page 11





       making a survey of A5-F2 stars for (1) an anomalous overabundance of
       the elements of praseodymium and neodymium, (2) the presence, at any
       level, of technetium or plutonium, and (3) an anomalously high ratio
       of barium to   zirconium.    Of  course,  if  a  candidate  star  is
       identified, a more detailed spectral analysis could be performed and
       compared with the predicted ratios.
