The properties of the yrast states for ^100-110Pd even–even (e–e) nuclei have been established. The relation between the moment of inertia 2ϑ/ℏ² and the square of the rotational energy (ℏω)² has been drawn to identify the back-bending that may occur at a certain state for each isotope. The relation between gamma-energy over spin Eγ/I as a function of spin I has been drawn to determine the evolution in each isotope ranging from vibration to rotational properties. The suitable limit in the interacting boson model IBM-1 has been used to calculate the yrast states for each isotope, which are then compared with the experimental results.
