ABSTRACT
The results of systematic nuclear resonance fluorescence experiments on heavy deformed and spherical nuclei at the bremsstrahlung facility of the Stuttgart Dynamitron accelerator are reported. The investigation of the fragmentation of the orbital M1 scissors mode in deformed odd-mass nuclei has been continued with high-precision measurements on [sup 166]Ho and [sup 163]Dy, revealing a lot of weak excitations distributed over the energy range 1.5–4 MeV. The investigation of the (2[sup +]x3[sup -]) two-phonon excitations in the Sn isotopic chain shows a very harmonic coupling of the phonons. The results for both, the even-even and the odd-mass Sn isotopes are in good agreement with QPM calculations. © 2000 American Institute of Physics.
