Title: Measuring the β-decay Properties of Neutron-rich Exotic Pm, Sm, Eu, and Gd Isotopes to Constrain the Nucleosynthesis Yields in the Rare-earth Region

Abstract

Abstract The β -delayed neutron-emission probabilities of 28 exotic neutron-rich isotopes of Pm, Sm, Eu, and Gd were measured for the first time at RIKEN Nishina Center using the Advanced Implantation Detector Array (AIDA) and the BRIKEN neutron detector array. The existing β -decay half-life ( T _1/2 ) database was significantly increased toward more neutron-rich isotopes, and uncertainties for previously measured values were decreased. The new data not only constrain the theoretical predictions of half-lives and β -delayed neutron-emission probabilities, but also allow for probing the mechanisms of formation of the high-mass wing of the rare-earth peak located at A ≈ 160 in the r -process abundance distribution through astrophysical reaction network calculations. An uncertainty quantification of the calculated abundance patterns with the new data shows a reduction of the uncertainty in the rare-earth peak region. The newly introduced variance-based sensitivity analysis method offers valuable insight into the influence of important nuclear physics inputs on the calculated abundance patterns. The analysis has identified the half-lives of ¹⁶⁸ Sm and of several gadolinium isotopes as some of the key variables among the current experimental data to understand the remaining abundance uncertainty at A = 167–172.

β-Delayed One and Two Neutron Emission Probabilities Southeast of ¹³²Sn and the Odd-Even Systematics in r-Process Nuclide Abundances

Journal Article Phong, V. H. ; Nishimura, S. ; Lorusso, G. ; ... - Physical Review Letters

Here, the β-delayed one- and two-neutron emission probabilities (P_1n and P_2n) of 20 neutron-rich nuclei with N≥82 have been measured at the RIBF facility of the RIKEN Nishina Center. P_1n of ^130,131Ag, ^133,134Cd, ^135,136In, and ^138,139Sn were determined for the first time, and stringent upper limits were placed on P2n for nearly all cases. β-delayed two-neutron emission (β2n) was unambiguously identified in ¹³³Cd and ^135,136In, and their P_2n were measured. Weak β2n was also detected from ^137,138Sn. Our results highlight the effect of the N=82 and Z=50 shell closures on β-delayed neutron emission probability and provide stringent benchmarks for newlymore »« less

β-delayed neutron emission of r-process nuclei at the N = 82 shell closure

Journal Article Hall, O. ; Davinson, T. ; Estrade, A. ; ... - Physics Letters B

Theoretical models of β-delayed neutron emission are used as crucial inputs in r-process calculations. Benchmarking the predictions of these models is a challenge due to a lack of currently available experimental data. In this work the β-delayed neutron emission probabilities of 33 nuclides in the important mass regions south and south-west of ¹³²Sn are presented, 16 for the first time. The measurements were performed at RIKEN using the Advanced Implantation Detector Array (AIDA) and the BRIKEN neutron detector array. The P_1n values presented constrain the predictions of theoretical models in the region, affecting the final abundance distribution of the secondmore » r-process peak at A ≈ 130.« less

$β$ -delayed neutron spectroscopy of ${}^{133}{In}$

Journal Article Xu, Z. Y. ; Madurga, M. ; Grzywacz, R. ; ... - Physical Review. C

The decay properties of ¹³³In were studied in detail at the ISOLDE Decay Station. The implementation of the Resonance Ionization Laser Ion Source allowed separate measurements of its 9/2⁺ ground state (^{133more » $$g$$}In) and 1/2^- isomer (^133$$m$$In). With the use of $$β$$-delayed neutron and $$γ$$ spectroscopy, the decay strengths above the neutron separation energy were quantified in this neutron-rich nucleus for the first time. The allowed Gamow-Teller transition 9/2⁺→7/2⁺ was located at 5.93 MeV in the ^133$$g$$In decay with a log $ft$ = 4.7(1). In addition, several neutron-unbound states were populated at lower excitation energies by the first-forbidden decays of ^133$g,m$In. We assigned spins and parities to those neutron-unbound states based on the $$β$$-decay selection rules, the log $ft$ values, and systematics.« less

Improving fission-product decay data for reactor applications: part I—decay heat

Journal Article Nichols, A. L. ; Dimitriou, P. ; Algora, A. ; ... - European Physical Journal. A, Hadrons and Nuclei (Online)

Effort has been expended to assess the relative merits of undertaking further decay-data measurements of the main fission-product contributors to the decay heat of neutron-irradiated fissionable fuel and related actinides by means of Total Absorption Gamma-ray Spectroscopy (TAGS - sometimes abbreviated to TAS) and Discrete Gamma-ray Spectroscopy (DGS). This review has been carried out following similar work performed under the auspices of OECD/WPEC-Subgroup 25 (2005–2007) and the International Atomic Energy Agency (2009, 2014), and various highly relevant TAGS measurements completed as a consequence of such assessments. Here, we present our recommendations for new decay-data evaluations, along with possible requirements formore »« less
