PPT-Charge radii of medium-mass nuclei using the atomic physics

Magdalena Kowalska CERN PHDept kowalskacernch below Outline 2 Laser spectroscopy on radioactive nuclei Optical isotope shifts A long way from isotope shifts to charge radii Takehome message . Which subatomic particles have a charge?. proton and electron. Which subatomic particles are the heaviest?. proton and neutron. Copper has 29 protons. If it has a +2 charge, how many electrons does it have?. Atoms, Elements, Molecules, Ions, and Compounds. Early in the 19. th. century John Dalton developed atomic theory. His theory explained the best available experimental data at that time. His theory has been modified since then with the discovery of other data, but his work was the initial ground work that we will examine first.. Topic 2.2. Review of Topic 2.1. X.
