Abstract

The double Penning trap mass spectrometer JYFLTRAP has been employed to measure masses and excitation energies for 11/2^\ensuremath- isomers in ¹²¹Cd, ¹²³Cd, ¹²⁵Cd, and ¹³³Te, for 1/2^\ensuremath- isomers in ¹²⁹In and ¹³¹In, and for 7^\ensuremath- isomers in ¹³⁰Sn and ¹³⁴Sb. These first direct mass measurements of the Cd and In isomers reveal deviations to the excitation energies based on results from \ensuremathβ-decay experiments and yield new information on neutron- and proton-hole states close to ¹³²Sn. A new excitation energy of 144(4) keV has been determined for ¹²³Cd^m. A good agreement with the precisely known excitation energies of ¹²¹Cd^m, ¹³⁰Sn^m, and ¹³⁴Sb^m has been found.
