AbstractAbstract
[en] Nucleocosmochronology is reviewed, emphasising its model-independent foundation and both the model-independent and dependent results. The long-lived radionuclides 232Th/238U and 187Re/187Os set a lower limit on the age of the Universe of 8.7 x 109 yr by their model-independent determination of the mean age of the elements. The short-lived chronometers 129I/127I, 26Al/27Al and 107Pd/110Pd paint a picture of the last nucleo-synthetic events that includes a supernova(e) association with the embryonic solar system. The possibility of elucidating this scenario by further development of these chronometers and also the 146Sm/142Nd and 247Cm/238U pairs is discussed. It is shown that intermediate-lived nuclides are in principle capable of describing the time dependence of the nucleosynthetic production function. However, the present situation does not allow serious model-independent constraints of this type. Nucleocosmochronology, when coupled with other independent determinations of the age of the Universe, is found to place a clear constraint on galactic evolution models in general. (author)
