void TGeoMixture::FillMaterialEvolution ( TObjArray population,
Double_t  precision = 0.001 
)
virtual

Fills a user array with all the elements deriving from the possible decay of the top elements composing the mixture.

Each element contained by <population> may be a radionuclide having a Bateman solution attached. The precision represent the minimum cumulative branching ratio for which decay products are still taken into account. To visualize the time evolution of each decay product one can use:

TGeoElement *elem = population->At(index);
TGeoElementRN *elemrn = 0;
if (elem->IsRadioNuclide()) elemrn = (TGeoElementRN*)elem;

One can get Ni/N1(t=0) at any moment of time. Ni is the number of atoms of one of the decay products, N1(0) is the number of atoms of the first top element at t=0.

Double_t fraction_weight = elemrn->Ratio()->Concentration(time);

One can also display the time evolution of the fractional weight:

elemrn->Ratio()->Draw(option);
