Abstract

Direct mass measurements of the low-spin 3/2⁻ and high-spin 13/2⁺ states in the neutron-deficient isotopes ¹⁹⁵Po and ¹⁹⁷Po were performed with the Penning-trap mass spectrometer ISOLTRAP at ISOLDE-CERN. These measurements allow the determination of the excitation energy of the isomeric state arising from the νi_13/2 orbital in ^195,197Po. Additionally, the excitation energy of isomeric states of lead, radon, and radium isotopes in this region were obtained from α-decay chains. These excitation energies complete the knowledge of the energy systematics in the region and confirm that the 13/2⁺ states remain isomeric, independent of the number of valence neutrons.
