“…For these transitions, in order to estimate the multipolarity, angular distributions were extracted from the spectra of the seven rings of GASP (35 • , 60 • , 72 • , 90 • , 108 • , 120 • , and 145 • ). Since the GASP array has many detectors, placed at many different angles, the angular correlation effects between any two γ rays are washed out, so that the intensity of any γ ray in the seven rings does not depend on the character of the gating transition(s), but follows the regular angular distribution of γ rays from oriented nuclei [14].…”

High-spin states in 155 Yb have been studied via the 144 Sm( 16 O ,5n) 155 Yb reaction at a beam energy of 118 MeV. One negative-parity and one positive-parity cascade built on the νf 7/2 and νi 13/2 states, respectively, are established for the first time. The structures observed in 155 Yb are compared with those in the neighboring N = 85 isotones and with semiempirical shell-model (SESM) calculations. According to adiabatic and configuration-fixed constrained triaxial covariant density functional theory (CDFT) calculations, a coexistence of prolate and oblate shapes is predicted to exist in 155 Yb.

“…In our case, the anisotropy is defined as A = W (72. Another way to determine the multipole of transitions is by γ -ray angular distribution from oriented nuclei (ADO) ratios [18]. The main advantage with the ADO ratio is that it is independent of the gating transition.…”

The structure of the low-and medium-spin levels of the 211 Po nucleus have been studied with in-beam γ -ray spectroscopy with the 208 Pb(α,n) 211 Po fusion-evaporation reaction. The level scheme was further extended with levels of the configurations π (h 9/2 ) 2 2 + −4 + ⊗ νg 9/2 , π (h 9/2 ) 2 8 + ⊗ νg 9/2 , π (h 9/2 ) 2 2 + −4 + ⊗ νi 11/2 , π (h 9/2 ) 2 2 + −4 + ⊗ νj 15/2 , π (h 9/2 f 7/2 ) 8 + ⊗ νg 9/2 , and π (h 9/2 ) 2 0 + ⊗ ν(g 9/2 ) 2 0 + (s 1/2 ) −1 . The single-particle neutron states νd 5/2 and νs 1/2 were also identified. Furthermore, a number of states feeding the low-spin structures were added.
