Neutron-induced 37Ar recoil ejection in Ca-rich minerals and implications for 40Ar/39Ar dating
The 40Ar/39Ar dating technique requires the transformation of 39K into 39Ar by neutron activation. Neutron activation has undesirable secondary effects such as interfering isotope production, and recoil of 39Ar and 37Ar atoms from their (dominant) targets of K and Ca. In most cases, the grains analy...
