Abstract

A low energy proton beam has been used to measure the B(E2) values of different levels in ¹²⁷I via Coulomb excitation process. The de-excitation gamma ray yields were measured with a 50 cm³ Ge(Li) detector placed at 55° to the incident proton beam. The iodine target was prepared by pressing KI into pellet form. The proton beam of 3.7 MeV energy was used to excite the levels at 202.8, 375.0, 418.0, 629.0 and 745.5 keV in ¹²⁷I. The measured values of B(E2) for the above levels are compared with the previous measurements available in literature.

Rotational Raman scattering in <sup>127</sup>I
1991, Nuclear Physics, Section A
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.
