This ratio returns to unity with a half life of 250 ky. Where the initial ratio is known and constant, this can be used as a further geochronometer. Unstable Nuclei and Radioactive Decay 61 (e) The total angular momentum pI of the system must be conserved, i.e. (pI )1 + ( pI )2 = ( pI )3 + ( pI )4 (4.8)Since there exist two types of angular momentum, one caused by orbital movement of the d.
