Title: $94 β$ -Decay Half-Lives of Neutron-Rich ${}_{55}{Cs}$ to ${}_{67}{Ho}$ : Experimental Feedback and Evaluation of the $r$ -Process Rare-Earth Peak Formation

Abstract

The β-decay half-lives of 94 neutron-rich nuclei ^{144 $$-$$ 151}Cs, ^{146 $$-$$ 154}Ba, ^{148 $$-$$ 156}La, 1^{50 $$-$$ 158}Ce, ^{153 $$-$$160}Pr, 156 $$-$$ 162 Nd, ^{159 $$-$$ 163}Pm, ^{160 $$-$$ 166}Sm, ^{161 $$-$$ 168}Eu , ^{165 $$-$$ 170}Gd, ^{166 $$-$$ 172}Tb, ^{169 $$-$$ 173}Dy, ^{172 $$-$$ 175}Ho, and two isomeric states ^{174 m}Er, ^{172 m}Dy were measured at the Radioactive Isotope Beam Factory, providing a new experimental basis to test theoretical models. Strikingly large drops of β -decay half-lives are observed at neutron-number N = 97 for ₅₈Ce, ₅₉Pr, ₆₀Nd , and ₆₂Sm, and N = 105 for ₆₃Eu, ₆₄Gd, ₆₅Tb, and ₆₆Dy. Features in the data mirror the interplay between pairing effects and microscopic structure. In conclusion, $$r$$-process network calculations performed for a range of mass models and astrophysical conditions show that the 57 half-lives measured for the first time play an important role in shaping the abundance pattern of rare-earth elements in the solar system.

94 {beta}-Decay Half-Lives of Neutron-Rich 55Cs to 67Ho: Experimental Feedback and Evaluation of the r-Process Rare-Earth Peak Formation

Journal Article Wu, J. ; Nishimura, S. ; Lorusso, G. ; ... - Physical Review Letters

Strikingly large drops of β-decay half-lives are observed at neutron-number N = 97 for ₅₈Ce, ₅₉Pr, ₆₀Nd, and ₆₂Sm, and N = 105 for ₆₃Eu, ₆₄Gd, ₆₅Tb, and ₆₆Dy. Lastly, features in the data mirror the interplay between pairing effects and microscopic structure. r-process network calculations performed for a range of mass models and astrophysical conditions show that the 57 half-lives measured for the first time play an important role in shaping the abundance pattern of rare-earth elements in the solar system« less

Proton Shell Evolution below ${}^{132}{Sn}$ : First Measurement of Low-Lying $β$ -Emitting Isomers in ${}^{123, 125}{Ag}$

Journal Article Chen, Z. Q. ; Li, Z. H. ; Hua, H. ; ... - Physical Review Letters

The β-delayed γ-ray spectroscopy of neutron-rich ^123,125Ag isotopes is investigated at the Radioactive Isotope Beam Factory of RIKEN, and the long-predicted 1/2^- β-emitting isomers in ^123,125Ag are identified for the first time. With the new experimental results, the systematic trend of energy spacing between the lowest 9/2⁺ and 1/2^- levels is extended in Ag isotopes up to N = 78, providing a clear signal for the reduction of the Z = 40 subshell gap in Ag towards N = 82. Shell-model calculations with the state-of-the-art V_MU plus M3Y spin-orbit interaction give a satisfactory description of the low-lying states in ^123,125Ag.more »« less

Production cross sections of elements near the $N = 126$ shell in ${}^{48}{Ca}$ -induced reactions with ${}^{154}{Gd}, {}^{159}{Tb}, {}^{162}{Dy}$ , and ${}^{165}{Ho}$ targets

Journal Article Mayorov, D. A. ; Werke, T. A. ; Alfonso, M. C. ; ... - Physical Review. C, Nuclear Physics

Excitation functions for shell-stabilized evaporation residues produced in 48 Ca -induced reactions with 154 Gd , 159 Tb , 162 Dy , and 165 Ho targets have been measured in experiments performed at the Cyclotron Institute at Texas A&M University. The examined energy range predominantly covers the 3 n and 4 n evaporation channels with higher cross sections measured for the 4 n products. The σ 4 n are nearly invariant within experimental uncertainty in reactions with 159 Tb , 162 Dy , and 165 Ho with the maxima at 12.6 ± 1.9, 12.6 ± 1.7, and 9.4 ± 1.3more »« less

Journal Article Stryjczyk, M. ; Tsunoda, Y. ; Darby, I. G. ; ... - Physical Review C

Here, shell evolution can impact the structure of the nuclei and lead to effects such as shape coexistence. The nuclei around ⁶⁸Ni represent an excellent study case, however, spectroscopic information of the neutron-rich, Z < 28 nuclei is limited. The goal is to measure γ-ray transitions in ⁶⁶Fe, ⁶⁶Co, and ⁶⁶Ni populated in the β– decay of ⁶⁶Mn to determine absolute β feedings and relative γ-decay probabilities and to compare the results with Monte Carlo shell model calculations in order to study the influence of the relevant single neutron and proton orbital occupancies around Z = 28 and N =more »« less
