Project

Laser separation of radioactive isotopes and nuclear isomers of europium (GA202/97/0445)

iNducedDrift Isotope Separation) method was chosen for Eu nuclear isomers separation. The LIDIS method is simple. Isotopic (isomeric) effects enable to tune a laser radiation so a way that the LID of atoms of two different...
