“…This spectrum is dominated by the 437-keV, 2 + 1 → 0 + , transition of 204 Hg with 9.5 × 10 7 counts. All other strong γ rays originate from 204 Hg excited states [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] as well and most of these are in coincidence with the ground-state transition (cf. Fig.…”

Available online xxxx Editor: V. Metag Keywords: γ ray spectroscopy Coulomb excitation Quadrupole collectivity Isospin degree of freedom Shell structureOne-phonon states of vibrational nuclei with mixed proton-neutron symmetry have been observed throughout the nuclear chart besides the mass A ≈ 200 region. Very recently, it has been proposed that the 2 + 2 state of 212 Po is of isovector nature. This nucleus has two valence protons and two valence neutrons outside the doubly-magic 208 Pb nucleus. The stable isotope 204 Hg, featuring two valence-proton and valence-neutron holes, with respect to 208 Pb, is the particle-hole mirror of 212 Po. In order to compare the properties of low-lying isovector excitations in these particle-hole mirror nuclei, we have studied 204 Hg by using the projectile Coulomb-excitation technique. The measured absolute B(M1; 2 +strength of 0.20 (2) μ 2 N indicates that the 2 + 2 level of 204 Hg is at least the main fragment of the 2 + 1,ms state. For the first time in this mass region, both lowest-lying, one-quadrupole phonon excitations are established together with the complete set of their decay strengths. This allows for a microscopic description of their structures, achieved in the framework of the Quasi-particle Phonon Model.

“…In other words, in the course of our analysis all higher-order corrections for vacuum polarization will be ignored. Applications of the Uehling potential to various atomic and muon-atomic systems can be found, e.g., in [6], [7] and [8] and referenes mentioned in these papers. Here we will not discuss such applications, since they are quite different from the goals of this work.…”

Properties and different representations of the Uehling potential are investigated. Based on these properties and by using our formulas for the Fourier transform of the Uehling potential we have developed the new analytical, logically closed and physically transparent procedure which can be used to evaluate the lowest-order vacuum polarization correction to the cross sections of a number of QED processes, including the Mott electron scattering, bremsstrahlung, creation and/or annihilation of the (e − , e + )−pair in the field of a heavy Coulomb center, e.g., atomic nucleus.
