Abstract
The p(pe− v)d, reaction (Q = 1.442 MeV) is examined in view of the possible Gamow Factor Cancellation (GFC) theorized by Kim and Zubarev (1995). The lifetime for the pep reaction in a metal hydride environment, such as FeH in the core of the earth, was calculated to be 2.54E(+12) yrs. The duration of the earth’s melting and degassing prior to the formation of the oceans can be calculated using the present ratio D/H = 1.5E(−4) for the oceanic value, the pep lifetime in Fe and the primordial ratio of D/H = 2.6E(−5). The time interval was calculated to be 630 ± 160 million years, yielding an oceanic formation age of 3.92 billion years ago. The d(pe−, v)t, reaction (Q = 5.474 MeV) was also examined in view of the subsequent decay of tritium to 3He and its possible role as a radiochronometer.
