the independent model used by meyer and schramm (here after m&s) for determining the age ofelements (chemical evolution) is extended. using new and extended definitions and including parametersignored by m&s, the galactic evolution equations are solved to determine the total duration ofnucleosynthesis,t. to be able to calculate the t t (mean age time for formation of elements to total ...
