ANALYSIS   The authors assumed that the counting yield of 20m Y   14597  2    7 
           and 10h Y to be the same, so the relative fission      14597  2    8 
           yields of the two radioisotopes can be calculated      14597  2    9 
           from the chain relations and the times of irradiation  14597  2   10 
           and decay.                                             14597  2   11 
COMMENT    Authors assigned 10h activity to Y-95, which was       14597  2   12 
           replaced by compiler by Y-93, taking into account      14597  2   13 
           editors' note 'This part of the chain has since been   14597  2   14 
           shown not to be of mass 95'.                           14597  2   15 
           For 20m Y authors did not give value for A, A=94 for   14597  2   16 
           20m Y taken from editors' note.                        14597  2   17
