Abstract

Elastic and Raman scattering of photons by ¹⁸¹Ta and ¹²⁷I are studied using the 11.4 MeV mono-energetic photon beam installed at the Mol BR2 reactor. For the strongly deformed prolate nucleus ¹⁸¹Ta the simple rotator model is re-investigated and found to be valid. The intrinsic quadrupole moment Q₀ derived from spectroscopic data by assuming a strong particle-surface coupling was found to be in agreement with the splitting of the giant dipole resonance, thus removing previous inconsistencies. When applying the same model to the oblate nucleus ¹²⁷I a severe discrepancy between experimental and predicted Raman cross sections was observed; this discrepancy is discussed in terms of nuclear-structure properties.
