176Lu: Cosmic clock and stellar thermometer
Description
The s-process nucleosynthesis of the isobar pair 176Lu/176Hf, a long-lived cosmic clock, is examined in conjunction with the s-only isotopes /sup 148,150/Sm, 154Gd, 160Dy, 170Yb, 186Os, and 192Pt. Expressions are derived which allow us to calculate the s-process age from measured quantities alone. A formula is specified which does not contain the population probability P to the 3.68 hr isometric state in 176Lu. This allows us to decide if 176Lu is, in addition to a cosmic clock, also a stellar thermometer
