Relativistic configuration-interaction density functional theory:Nonaxial effects on nuclear ββ decay
【摘要】 <正>Nuclear ββ decay is a second-order weak process in which an even-even nucleus decays to its neighboring even-even nucleus by turning two neutrons to two protons while emitting two electrons. A nucleus undergoes such decay by two distinguishable modes, i.e., the two-neutrino ββ (2νββ) and the neutrinoless ββ(0νββ) decays. The 2νββ decay is a lepton-number-conserving process and has been observed in a group of nuclei. The yet unobserved 0νββ decay is a lepton-number-violating process and its observation would signal the violation of lepton number, establish the Majorana nature of neutrinos, and shed light on the matter dominance in the universe.
