Abstract
A systematic analysis of the spherical-to-deformed shape phase transition in even-even rare-earth nuclei from to is carried out in the framework of the interacting boson model. These results are then used to calculate nuclear radii and electric monopole () transitions with the same effective operator. The influence of the hexadecapole degree of freedom ( boson) on the correlation between radii and transitions thus established is discussed.
