Properties of 20984Po125 as Observed in the Decay of 209At
TLDR
In this article, the electron capture decay of 209At has been studied and the main part of the decay proceeds to a 9/2+ level at 2 312 keV, which is interpreted as a core-excited state.Abstract:
209Po, with one neutron less and two protons more than 208Pb, has been studied in the electron capture decay of 209At. Most of the observed states below 2 MeV excitation can be interpreted as having dominant components corresponding either to one-neutron-hole states or to the coupling of a p1/2 neutron hole to (h9/2)2J ≠ O configurations. Several M1 and E2 transition rates were measured. These, as well as level energies, generally show good agreement with theory. The main part of the 209At electron capture decay proceeds to a 9/2+ level at 2 312 keV, which is interpreted as a core-excited state.read more

Internal conversion tables part I: K-, L-, M-shell conversion coefficients for Z=30 to Z=103
R.S. Hager,E.C. Seltzer +1 more
TL;DR: In this article, the internal conversion coefficient, number of electrons per photon emitted in a nuclear transition, is presented from a new relativistic selfconsistent field calculation which takes into account finite nuclear size, hole and exchange effects, experimental electron binding energies, and vacuum polarization.

Energy levels of Bi210 and Po210 and the shell-model residual force
Yeong E. Kim,John O. Rasmussen +1 more
TL;DR: In this paper, the low-lying energy level spectra of Bi/sup 210/ and Po/sup 208/ were calculated by using the j-j coupling shell model and a residual nucleon-nucleon Gaussian potential without a hard core deduced from the free two-Nucleon potentials of BlattJackson and Brueckner-Gammel-Thaler.

The 3−×3− two-phonon quartet and the proton pairing vibration in 208Pb
TL;DR: In this article, the observed large quadrupole moment of the collective 3 − state in 208 Pb was found to imply a considerable splitting of the two-octupole-phonon quarter.
