Resonance ionization spectroscopy of fermium (Z=100)☆☆☆

Laser spectroscopy has been applied for the first time to measure resonant transition frequencies of fermium (Zs 100). A number of 2.7=10 atoms was electrodeposited on a Ta filament and covered with a 1 mm Ti layer. Fm 10

Isotope shift measurement at 244fAm

AbstractOptical isotope shift measurements have been performed at the 244fAm fission isomers (T1/2=1 ms) with low target production rates of 10/s employing resonance ionization spectroscopy in a buffer gas cell. The isotope shift ratio IS244f,241/IS243,241 = 42.0(9) has been measured at the 500.02 nm transition. A change in the nuclear mean charge radius
