The isotopic shifts of the 576.5-nm line of the isotopes 141»i42.i43,i44,i45 ^ ^ауе measured by laser resonant photoionization of atoms on line with a mass separator and a proton synchrocyclotron. These are the first such measurements. In addition, a selective stepwise ionization of142m Eu has been achieved for the first time, demonstrating the possibility of a laser separation of isomers.
