“…This value is consistent within errors with the value of δ 2 α = 37(4) keV for the l = 0 decay of the neighboring odd-A lead nucleus, 181 Pb [31]. Table III shows a comparison of different α-decay properties for 179 Pb obtained from the present work and from Ref.…”

The very neutron-deficient isobars 179 Pb and 179 Tl have been produced using the fusion-evaporation reactions 104 Pd( 78 Kr,xpyn), where x 1 and y 2. The gas-filled separator RITU was employed to transport and separate the recoiling nuclei of interest from the scattered beam and unwanted products. The GREAT spectrometer was used to study the decay properties through α-α and α-γ correlations, which has allowed the ground state of 179 Pb to be assigned as I π = 9/2 − . The decay of 179 Pb was measured to have an α-particle energy and half-life of E α = 7348(5) keV and t 1/2 = 2.7(2) ms, respectively. A search for a νi 13/2 state in 179 Pb was performed, but only a limit of excitation energy and half-life was obtained. In 179 Tl a t 1/2 = 114 +18 −10 ns isomeric state, likely at an excitation energy of 904.5(9) keV, was identified and is tentatively assigned to be a 9/2 − proton intruder state.

The first identification of the β-delayed fission of this isotope was made and its probability P βDF ( 178 Tl) = 0.15(6)% was determined. An asymmetric fission fragment mass distribution of the daughter isotope 178 Hg (populated by the β decay of 178 Tl) was deduced based on the measured fission fragment energies. The fine-structure α-decay pattern of 178 Tl allowed the low-energy states in the daughter nucleus 174 Au to be studied.

“…In fact, the spin and parity cannot be unambiguously determined due to the unpaired nucleons for the case of odd-A and odd-odd nuclei. Some detailed decay schemes are deduced tentatively based on the available experimental cases [8][9][10][11][12][13]. On the other hand, tentative assignments of the spin and parity for some isotopes are taken from the systematic trends in neighboring nuclides [58].…”

“…Besides naturally occurring α emitters, plenty of unstable nuclei have been produced artificially in nuclear reactions. Within the fusion-evaporation reactions, considerable experimental data on α emissions for various isotopes close to the proton drip line have been acquired for the first time or with improved accuracy [8][9][10][11][12][13][14][15], including the recent discovery of the new nuclide 161 Os [15]. In fact, some neutron-deficient isotopes approaching the proton drip line were originally produced to pursue new cases of proton emission [8].…”

Recently discovered α decays with new or improved data, covering naturally occurring α emitters with long lifetimes, short-lived ones approaching the proton drip line, and decays of heavy and superheavy elements, have been studied in a systematic investigation within the modified two-potential approach for deformed nuclei by constructing the microscopic double-folding potential. It is found that the experimental half-lives are well reproduced in the density-dependent cluster model. Some predictions on natural α emitters and α decays of several proton emitters are made in this study. Moreover, the α-decay half-lives of even-even superheavy nuclei with Z = 110-114 and N = 184-194 are estimated to pursue the quite stable nuclei around the proton Z ∼ 114 and neutron N ∼ 184 shell closures. These predictions can be useful for future experiments aimed at searching for long-lived natural elements.
