New lifetime measurements inPd109and the onset of deformation atN=60

“…These along with the lowest 7/2 − , which is the only negative-parity state strongly populated in the β decay of 109 Rh, and the 5/2 + 2 state, which has a dominant β-feeding intensity systematically across the Pd chain [21,[25][26][27][28][29][30], are highlighted below. A.…”

“…Single-neutron transfer [21,[24][25][26][27][28][29] and high spin studies [41][42][43][44][45][46][47][48] indicate that one of these levels consistently displays a νg 7/2 single-particle character, while the other can be described as a νd 5/2 ⊗ 2 + 1 configuration. This distinction is based on the observed spectroscopic strengths (Table II) and band structures connected to them (Fig.…”

“…5). The exception to this is in 107 Pd where the level structures seem to be mixed due to the close proximity in energy of the 7/2 + states as well as the isolated occurrence of a third low-lying 7/2 + state in the same vicinity [21,27]. The energy systematics of the two 7/2 + states in the Pd isotopes compared to the even-even Pd 2 + 1 levels are shown in Fig.…”

“…Note that the groundstate spins and parities for the Pd isotopes in this mass range are all 5/2 + . Of particular interest from a nuclear structure standpoint are the 7/2 + states which appear in pairs at relatively low energies systematically across the Pd isotope chain [21][22][23][24][25][26][27][28][29][30] and seem to display two distinct structures. Other levels of interest are the lowest 7/2 − , which is the only negative-parity state strongly populated in the β decay of 109 Rh, and the 5/2 + 2 state, which has a dominant β-feeding intensity systematically across the Pd isotopic chain [21,[25][26][27][28][29][30].…”

“…The purple levels highlight the 5/2 + 2 states and associated band structure observed in 105 Pd [45]. [21,[24][25][26][27][28][29]. Although based on Fig.…”
