Calculation of the time interval of galactic nucleosynthesis
from its beginning to the formation of the solar system ( ''age of
the galaxy'' ) by primary nuclear yield ratios based on recent
mass formulas result to  about 10*10^8a. Recalculating this with more
recent decay data including spontaneous fission one obtains
more than 70*10^8a, in much better agreement with other astronomical
evolution data. The influence of the termination of the r-process
path by neutron-induced fission may be nevertheless the decisive
property and will be taken into account in further calculations.
