摘要：

Nuclear resonance fluorescence experiments have been performed on the nucleus 48Ti. Unpolarized bremsstrahlung of 4.1 and 11 MeV and partially linearly polarized bremsstrahlung of 12 and 14 MeV endpoint energy, respectively, served as the photon sources. The scattered photons were detected by high-resolution Ge γ-spectrometers. Precise excitation energies, decay branching ratios, and ground-state decay widths of numerous previously unknown spin-1 states have been extracted. Model-independent parity assignments could be achieved for the strongest transitions. The results are compared with data from previous (γ, γ') work, from recent (e, e') and (p, p') experiments, and with theoretical predictions. © 1990.
