摘要：

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