Pertubed magnetic spectrum of ferrous and ferric alloys

Isotopes of iron Isotopes of cobalt 14.4keV = 97.8 ns The observed sample is not radio active Range gamma Spectroscopy E= hc /lambda Doppler effect Energy modulation by Doppler Magnetic hf splitting Isomer shift = = charge density at quadrupole splitting = = charge symmetry magnetic hyperfine coupling = = electron spin density Shift depend Valence electron shield nuclear potential Fe(II) s = 0 Nature of Ligands

Excellent lecture

Acoustic resonance between two tuning forks vs same frequency Nuclear gamma ray absorption Lorentzians High energy photons cannot be absorbed Gamma resonance cannot be absorbed with gases Recoilless emission and absorption

Vielen Dank!!! You really explained the concepts so well!!!

Many people are so compassionate that poverty exists .......
