Lifetime and relative g factor measurements in $^{104,106,108}$Pd isotopes

The purpose of this research was the proof-of-principle for the new g-plunger technique to measure the deorientation and the lifetime of a state after an inverse kinematics reaction. The deorientation effect is due to the hyperfine interaction between the nuclear spin and the surrounding electron configurations. The attenuation of $\gamma$-ray angular distributions has been measured for the $2^+_1$ and $4^+_1$ states of $^{104}$Pd, $^{106}$Pd and $^{108}$Pd. The beams with energies of 324~MeV, 330~MeV and 336~MeV, respectively, were Coulomb excited into their $2^+_1$ state on a $^{24}$Mg target. Forward scattered Mg was detected after passing a Cu foil, which served as a stopper for the beam. We measured the time-dependence of the attenuation as a function of distance, in parallel to measuring the lifetimes of the $2^+_1$ and $4^+_1$ states. This attenuation is used to measure the g factor of the decaying states relative to each other. In this work, hyperfine parameters have been calibrated for the Pd isotopes. The results of this work and a discussion of the parameterization used to fit the data in this work will be presented.
