Nuclear g-factor measurement for the low-lying state in $^{109}$Rh using On-line TDPAC technique and RF-IGISOL technique

ORAL

Abstract

To extend the studies on neutron-rich nuclei, we have developed an RF-IGISOL technique, which is combination of the gas catcher technique and the electrical field guiding technique with a large volume gas cell. As the first step to such approach, we are planning and trying the systematic measurement of g-factor in the neutron rich nuclei extracted as an radioactive beam from our RF-IGISOL at Tohoku University. The g-factor measurement for the low-lying state of $^{109}$Rh ($E_{x}$~=~225.98~keV, $T_{1/2}$~=~1.66~$\mu$s) is the first on-line experiment with our RF-IGISOL system. The g-factor for this state has been determined to be $g~=~$0.78~$^{+0.17}_{-0.03}$~$\mu_{N}$ by the on-line TDPAC method. In this contribution, the details of experimental results will be reported.
