The properties and structure of nuclei with equal number of protons and neutrons have been in the last decades an intense field of research, both experimentally and theoretically. The structure of these nuclei provide essential infomation, among other things, about the isospin symmetry of the nuclear force as well as on proton-neutron correlations. As an example, the isobaric analogue states in...

Gamow-Teller (GT) transitions are caused by the most common weak interaction of spin-isospin (στ) type with ΔL = 0. Since spin and isospin are unique quantum numbers in nuclei, GT transitions represent very important nuclear response. GT transitions are studied by the β decay and charge-exchange (CE) reactions. The β decay has a direct access to the absolute GT transition strengths...

Through the studies of Fermi transitions between 0+ analog states with T = 1 (superallowed transitions), nuclear physics provides a valuable test of the Standard Model of particle physics. These transitions depend only on the vector part of the weak interaction, and according to the conserved vector current (CVC) hypothesis, their strength Ft is a constant. Then this value is used to determine...
