Investigation of internal conversion anomalies in 234Pa [PDF]

open access: yesЯдерна фізика та енергетика, 2006
In the work presented the energy and K-shell internal conversion coefficient for γ-transition with the energy of 112,8 keV in 234Pa were measured. The following estimates for Eγ = 112,790 ± 0,002 keV and aK = 0,220 ± 0,011 have been obtained.

Internal conversion coefficients at gamma-ray threshold energies

open access: yesNuclear Data Sheets. Section A, 1967
Internal conversion coefficients, for threshold values of the gamma-ray energy, are presented for the K-shells, L-subshells, and M-subshells for all values of Z in the range 6 ≤ Z ≤ 95, and for the first five electric and magnetic multipoles.

Internal Conversion and Vibrational Energy Redistribution in Chlorophyll A

open access: yesThe Journal of Physical Chemistry B, 2015
We have computationally investigated the role of intramolecular vibrational modes in determining nonradiative relaxation pathways of photoexcited electronic states in isolated chlorophyll A (ChlA) molecules. To simulate the excited state relaxation from the initially excited Soret state to the lowest excited state Qy, the approach of nonadiabatic ...
