Hyperfine Interactions of Excited Nuclei in Atomic Systems

Identification of excited structures in proton unbound nuclei 173,175,177Au: shape co-existence and intruder bands

“…Their ordering follows from the relative intensities within a given cascade. Since γ -ray angular distributions were found to be nearly isotropic within statistical uncertainties, presumably as a result of de-orientation as the ions recoil into vacuum [29], it was not possible to obtain useful information on transition multipolarities. However, γ -ray intensity balances were used to extract total electronconversion coefficients, α T , in order to distinguish between E1, M1 or E2 character for transitions with energies below about 250 keV for which the conversion coefficients are significantly different.…”
