40Ca20n20pIsovector Giant Dipole ResonanceAnalogous to charge distributionsMonopole L=0Dipole L=1Quadrupole L=2Octupole L=3Etc.There should be lots of “Giant Resonances”Isovector (n’s and p’s 180 o out of phase)Isoscalar (n’s and p’s in phase)Spin (spin up and down 180 o out of phase)
Shape Oscillations“Giant Resonance”1. Many Nucleons involved in motion (~ 10 in 40 Ca).2. Contains “most of” strength for that multipole.
