Dear group

I would like a eleghant solution of this iterative process (perhaps
using NestList or FoldList}:

In[1]: First[IsotopeData["U238", "DaughterNuclides"]]
Out[1]: "Thorium234"
In[2]: First[IsotopeData[%, "DaughterNuclides"]]
Out[2]:"Protactinium234"
In[3]: First[IsotopeData[%, "DaughterNuclides"]]
Out[3]: "Uranium234"

and so on n times (the best solution would be if the process stop when
find that there not more isotopes,  that is when Out[n] = { })

and them

{"U238", "Protactinium234",  "Uranium234", ...}

Any help?

Guillermo
