From total neutron cross sections to nuclear charge radii - Part 1

$\textbf{Historical overview}$. War and peace. The foundation of the International Atomic Energy Agency. Total neutron cross sections; $\textbf{matter radii}$; correlation with binding energy. Visit to Ioffe Institute: K$_\alpha$ Isotope Shift $\rightarrow$ $\delta r^2_{charge}$; other methods. Fine structure in $\textbf{charge radii}$ along isotopic series: shell effects, odd-even, deformation. Fine structure along isotonic, isobaric, isosymmetric series: $\textbf{Table I}$. Comparison of experiment to theory; neutron skins calculated. Difference between r$_{el}$ and r$_{mu}$. Evaluation procedures investigated: $\textbf{Table II}$. Comparison of evaluation methods. $\textbf{Table III}$. With completion: $\textbf{Table IV}$. Application of constraints: $\textbf{Table V}$. Moments of the two-parameter Fermi charge distribution. Calculation of Fermi parameters from charge moments. $\textbf{Table VI}$. with $\delta \langle r^2 \rangle$. Correlation of nuclear charge radii with other nuclear observables. The proton radius puzzle. $\textbf{Problems}$. Dispersion correction in electron scattering. Consequences of the proton radius puzzle: a) normalized data; b) charge radius formulae. Recommendation of radius formulae. $\textbf{Future}$: $\textit{Weak ($\approx$ neutron) rms radii from parity violating electron scattering?}$
