The excited states in ~(190)pt were populated via the ~(176)Yb(~(18)O,4n)reaction at bombarding energies of 95 and 88 MeV.The ~(18)O beam was provided by the tandem accelerator at the Japan Atomic Energy Agency (JAEA).The target is an isotopically enriched ~(176)Yb metallic foil of 2.1 mg/cm~2 thickness with a 7.6 mg/ cm~2 Pb backing to avoid the Doppler shift of emittingγrays.In-beamγrays were detected by the detector array of JAEA,comprising 12 HPGe’s with BGO anti-Compton shields.The detectors were calibrated

The excited states in ~ (190) pt were populated via the ~ (176) Yb (~ (18) O, 4n) reaction at bombarding energies of 95 and 88 MeV.The ~ (18) O beam was provided by the tandem accelerator at the Japan Atomic Energy Agency (JAEA). The target is an isotopically enriched ~ (176) Yb metallic foil of 2.1 mg / cm ~ 2 thickness with a 7.6 mg / cm ~ 2 Pb backing to avoid the Doppler shift of the emitting gamma. -beamγrays were detected by the detector array of JAEA, comprising 12 HPGe’s with BGO anti-Compton shields. The detectors were calibrated
