Abstract

At times from around \(10^{-2}\) s through the first several minutes after the Big Bang, the temperature passed through the range from around 10 to below \(10^{-1}\) MeV. During this period protons and neutrons combined to produce a significant amount of \(^4\mathrm{He}\)—one quarter of the universe’s nuclei by mass—plus smaller amounts of deuterium (D, i.e., \(^2\mathrm{H}\)), tritium (\(^3\mathrm{H}\)), \(^3\mathrm{He}\), \(^6\mathrm{Li}\), \(^7\mathrm{Li}\), and\(^7\mathrm{Be}\).
