Osaamistavoitteet
At the end of this course, students will be able to list common nuclear ground state property observables (mass, spin, electromagnetic moments, charge radii etc.) and relate these to the underlying nuclear structure. Students will be able to use the interaction Hamiltonian associated with the magnetic dipole and electric quadrupole moments to calculate the energy splitting in atomic levels, and show how hyperfine structure arises from transitions between these levels. They will be able to use first order perturbation theory to calculate the Field shift and combine with the mass shift to extract isotope shifts. They will be able to identify different types of lasers the basic operation in connection to the Einstein coefficients as well as discuss different techniques of laser spectroscopy including Doppler-free methods and in-source spectroscopy. Students will be able to identify the different broadening processes associated with atomic transitions and the environment, calculate the selectivity in a multi-step excitation scheme, iIdentify different types of ion traps used in nuclear physics and explain working principles of Paul and Penning traps and multi-reflection time-of-flight separators as well as describe ion motion in a Penning trap and utilize the motions to purify ion samples or measure ion’s mass.
