Splitting Of Giant Dipole Resonance Research Articles

The configurational splitting of giant dipole resonance

This review considers the history and meaning of the phenomenon of configurational splitting of giant dipole resonance in light nuclei, which was first discovered a quarter of a century ago and induced profound changes in the commonly accepted understanding of the structure of light nuclei and the mechanisms of their high-energy excitations. The experiments that led to the discovery of this phenomenon are described. The present status of the phenomenon of the configurational splitting of nuclear giant dipole resonance is discussed and directions of its future studies are outlined.

Photodisintegration of Hg isotopes

Yields of photonuclear reactions of several Hg isotopes are measured on a bremsstrahlung photon beam with a maximal energy of 19.5 MeV using a gamma-activation analysis. Cross sections of photonuclear reactions on stable Hg isotopes are calculated within bonds of the collective model taking isospin splitting of giant dipole resonance into account. The experimental results are compared with the results of theoretical calculations and earlier experimental studies.
