These measurements allow the determination of the excitation energy of the isomeric state arising from the $\\nu$i$_{13/2}$ orbital in $^{195,197}$Po. Additionally, the excitation energy of isomeric states of lead, radon, and radium isotopes in this region were obtained from $\\alpha$-decay chains. The new excitation energies co","authors_text":"A.
