“…In the present configurationconstrained calculations, only the deformed high-spin states can be treated. In 192 At, a 9 − or 10 − isomer was observed with an oblate shape suggested [30]. However, our calculations give oblate 10 + and prolate 10 − states (see Table III).…”

We investigate the role of two-quasiparticle isomeric states along the proton drip line, using configurationconstrained potential-energy-surface calculations. In contrast to even-even nuclei, odd-odd nuclei can have coexisting low-lying two-quasiparticle states. The low excitation energy and high angular momentum can lead to long-lived isomers. Also, because of the hindrance by spin selection, the probabilities of β and proton decays from high-spin isomers can be reduced significantly. The present calculations reproduce reasonably well the available data for observed isomers in such nuclei. Unobserved high-spin isomers are predicted, which could be useful for future experimental studies of exotic nuclei at and beyond the proton drip line.

Excited states of 195 At have been studied by means of in-beam γ -ray spectroscopy and the recoil-decay tagging technique. A strongly coupled rotational band feeding the α-decaying 7/2 − state via unobserved transitions was identified. This band is presumably built on the oblate proton I π = 13/2 + state. Confirming earlier measurements, α decays from the 1/2 + and 7/2 − states were observed. Additionally, an E3 branch competing with the α decay of the 7/2 − state was inferred. Also α decays of the odd-odd isotopes 194,196 At were examined.

“…Details of the experimental conditions are given in Table I. In these experiments we also obtained new data for 194 At [15] and 192 At [16]. During production of 194 Po, several beam energies were used.…”

“…A more recent study, containing both in-beam and delayed γ -ray spectroscopic measurements, was performed at the gas-filled recoil separator RITU at JYFL (Finland) [12]. Based on prompt γ -ray data, the ground-state band was extended up to the (16 + ) level and the former (11 − ) level was reassigned to 12 + and moved to the ground-state band. Moreover, a side band up to a (10) level was established.…”

Isomeric states in194 Po and 192 Po were studied at the velocity filter SHIP. Po. Several new γ -ray transitions were attributed to the isomers and γ -γ coincidences for both isomers were studied for the first time. The 459-keV transition earlier, tentatively proposed as de-exciting the isomeric level in 194 Po, was replaced by a new 248-keV transition, and the spin of this isomer was reassigned from (11 − )to(10 − ). The de-excitation of the (11 − ) isomeric level in 192 Po by the 154-keV transition was confirmed and a parallel de-excitation by a 733-keV (E3) transition to (8 + ) level of the ground-state band was suggested. Moreover, side feeding to the (4 + ) level of the ground-state band was proposed. The paper also discusses strengths of transitions de-exciting 11 − isomers in neighboring Po andPbisotopes.
