| Abstract: | The isomer shift in the optical transition Eu II 4f7(8S 7 2/o )6p3/2 (7/2,3/2)4?4f7 (8S 7 2/o )5d9D 4 o , λ=6O4.95 nm, has been measured between the isotope152gEu(3?) and its isomer152mEu(0?). From the valuev(152gEu)–v(152mEu)=736(10) MHz the deformation parameter of152mEu has been estimated to be152mβ?+0.25. This value is smaller than152gβ as obtained from isotope shift measurements and the spectroscopic quadrupole moment. The influence of the shape difference on the decay of152mEu is discussed. |
