“…It should be noted that these isotopes belong to the region of neutron-rich short-lived nuclei and the precise determination of their spectra of excited states is a complex experimental task. Low-lying excitations J P = 13/2 − , 17/2 − , 21/2 − are defined with good reliability and interpreted as the (1h 9/2 ) 5π configuration in 213 Fr [17] and the (1h 9/2 ) −3π configuration in 215 Ac [18]. Our calculations show the authenticity of this interpretation.…”

Abstract. Excited states in low-energy spectra in nuclei near 208 Pb are considered. The pure ( j = 9/2) n configuration approximation with delta-force is used for ground state multiplet calculations. The multiplet splitting is determined by the pairing energy, which can be defined from the even-odd straggering of the nuclear masses. For the configurations with more than two valence nucleons, the seniority scheme is used. The results of the calculations agree with the experimental data for both stable and exotic nuclei within 0.06-6.16%. Due to simplicity and absence of the fitted parameters, the model can be easily applied for studies of nature of the excited states in a wide range of nuclei.

“…Similarly, a value of I π = 9/2 − is suggested for the 219 At ground state, based on the low hindrance factor of the α decay of 219 At g to 215 Bi g (HF = 1.1) [26]. The ground state of 215 Bi is presumed to have I π = (9/2 − ), in view of both the strong population of the 11/2 + state in its β decay to 215 Po and the much lower population of the 5/2 + state [26].…”

The quantum phase transitional behavior of the spherical shell model mean-field plus the geometric quadrupole-quadrupole and standard pairing model within a single-j shell is analyzed in detail. Various quantities, such as low-lying energy levels, some typical energy ratios, the overlaps of the excited states with those of the corresponding limiting cases, B(E2) values and electric quadrupole moments of some low-lying states and their ratios, as functions of the control parameter of the model in a j = 15/2 shell are calculated as an example, in which only a crossover occurs due to the Pauli exclusion. The results show that there are noticeable changes within the crossover region of the rotation-like to the pair-excitation (superconducting) phase transition, especially in the half-filling case. As application to realistic nuclear systems, a chain of isotones 212 Rn-213 Fr-214 Ra-215 Ac is chosen to be described by the model with valence protons in the 1h 9/2 shell. As far as the lowlying energy levels, the experimentally observed B(E2) values, and the electric quadrupole moment within the yrast band are concerned, these nuclei seem fitted reasonably well. The results indicate that these nuclei are all within the rotation-like to the pair-excitation phase transition near to the crossover point.
