Abstract: | The optical isotope shifts between 46Ti, 48Ti and 50Ti have been measured for eight 3d 3 4s a 5F-3d 2 4s 4p y 3 F lines of titanium by use of a Doppler-free experiment. By contrast with the positive shifts previously measured for 3d 2 4s 2 a 3 F-3d 2 4s 4p z 5 D lines, these shifts are negative and reveal the presence of large negative specific mass shifts attributed to a d-p electron jump. The interpretation of the present measurements and of former ones is made by means of Hartree-Fock calculations. |
