“…Plenty of experimental methods with different sources are employed to derive the nuclear size, for instance, high-energy elastic electron scattering (e − ) [24,25], muonic atom Xrays (u − ) [26][27][28], high-resolution laser spectroscopy (GSI) [29], optical isotopes shift (OIS) and K α X-rays isotopes shift (K α IS) [30], highly-sensitive Collinear Resonance Ionization Spectroscopy (CRIS) [31,32]. Besides, the quantities of charge radii can also be extracted indirectly from the experimental observations of nuclear decay , such as α-decay properties [33][34][35][36][37], cluster or proton emission data [38].…”
