| Abstract: | We report the first measurements of the hyperfine splitting of the fine structure levels 3d 5'4s a 5 S 2 and 3d 5 4p z 5 P 1,2,3 0 in singly ionised manganese in a collinear fast ion beam-laser experiment. The ions are excited by the intracavity frequency doubled output of a ring dye laser. The observed linewidth is sufficiently narrow to identify all hyperfine components of each fine structure level. |
