Abstract

Results of a photon scattering experiment on 112 Sn using bremsstrahlung with an endpoint energy of E0=3.8MeV are reported. A J=1state at Ex=3434(1 keV has been excited. Its decay width into the ground state amounts to Γ0=151(17)
meV, making it a candidate for a [2+⊗3−]1−two-phonon state. The results for
112 Snare compared with quasiparticle-phonon model calculations as well as the systematics of the lowest lying 1−states established in other even-mass tin isotopes. In contrast to findings in the heavier stable even-mass Sn isotopes, no
2+states between 2 and 3.5 MeV excitation energy have been detected in the present experiment.
