Abstract
The properties of the yrast states for Pd100-110 even-even (e e) nuclei have been established, The relation between the moment of inertia 2 theta/(h) over bar (2) and the square of the rotational energy ((h) over bar omega)(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 E gamma/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.
