Title: Total absorption spectroscopy measurement on neutron-rich ^74,75Cu isotopes

Abstract

This paper reports on the first β-decay study of ^74,75Cu isotopes using the technique of total absorption spectroscopy (TAS). The experiment was performed at the National Superconducting Cyclotron Laboratory at Michigan State University using the Summing NaI(Tl) (SuN) detector. The Cu isotopes are good candidates to probe the single-particle structure in the region because they have one proton outside the Z = 28 shell. Comparing the β-decay intensity distributions in the daughter Zn isotopes to the theoretical predictions provides a stringent test of the calculations. The nuclei in this region are also identified as playing an important role in the astrophysical r-process. Furthermore, the measured β-decay intensity distributions provide essential nuclear physics inputs required to better understand heavy element nucleosynthesis.

β-decay feeding intensity distributions of ^71,73Ni

Journal Article Persch, C. F. ; DeYoung, P. A. ; Lyons, S. ; ... - Physical Review C

This paper presents the β-decay feeding intensity distribution and Gamow-Teller transition strength distribution of ^71,73Ni. These quantities were measured using the technique of total absorption spectroscopy at the National Superconducting Cyclotron Laboratory with the Summing NaI(Tl) detector. These measurements provide sensitive constraints to theoretical models used to predict β-decay properties far from stability for astrophysical applications. Specifically, for the astrophysical r process, the majority of the involved nuclei are not accessible by current facilities, and the nuclear input is mainly provided by theory.

β-decay feeding intensity distributions for ^103,104mNb

The β decays of ^103,104mNb were studied with the Summing NaI(Tl) (SuN) detector at the National Superconducting Cyclotron Laboratory. The β-decay feeding intensity distribution I_β(E) for each isotope was extracted by measuring γ rays in coincidence with an emitted electron. The I_β(E) was extracted via the total absorption spectroscopy technique. The I_β(E) for each nucleus was compared to predictions made by the quasiparticle random-phase approximation (QRPA) model which is commonly used to calculate β-decay properties for astrophysical applications. The main goal was to provide experimental data for neutron-rich nuclei, relevant to the astrophysical r process. In addition, the extracted β-decaymore »« less

β Decay of ⁶¹V and its Role in Cooling Accreted Neutron Star Crusts

Journal Article Ong, W. -J. ; Brown, E. F. ; Browne, J. ; ... - Physical Review Letters

The interpretation of observations of cooling neutron star crusts in quasipersistent x-ray transients is affected by predictions of the strength of neutrino cooling via crust Urca processes. The strength of crust Urca neutrino cooling depends sensitively on the electron-capture and β -decay ground-state-to-ground-state transition strengths of neutron-rich rare isotopes. Nuclei with a mass number of A = 61 are predicted to be among the most abundant in accreted crusts, and the last remaining experimentally undetermined ground-state-to-ground-state transition strength was the β decay of ⁶¹V. This Letter reports the first experimental determination of this transition strength, a ground-state branching ofmore »« less

Total absorption spectroscopy of the β decay of ^101,102Zr and ¹⁰⁹Tc

Journal Article Dombos, A. C. ; Spyrou, A. ; Naqvi, F. ; ... - Physical Review C

The β decay of ^101,102Zr and ¹⁰⁹Tc was studied using the technique of total absorption spectroscopy. The experiment was performed at the National Superconducting Cyclotron Laboratory using the Summing NaI(Tl) (SuN) detector in the first-ever application of total absorption spectroscopy with a fast beam produced via projectile fragmentation. The β -decay feeding intensity and Gamow-Teller transition strength distributions were extracted for these three decays. The extracted distributions were compared to three different quasiparticle random-phase approximation (QRPA) models based on different mean-field potentials. A comparison with calculations from one of the QRPA models was performed to learn about the ground-state shapemore »« less

²⁵Siβ⁺-decay spectroscopy

Journal Article Sun, L. J. ; Friedman, M. ; Budner, T. ; ... - Physical Review C

Background: β-decay spectroscopy provides valuable information on exotic nuclei and a stringent test for nuclear theories beyond the stability line. Purpose: To search for new β-delayed protons and γ rays of ²⁵Si to investigate the properties of ²⁵Al excited states. Method: ²⁵Si β decays were measured by using the Gaseous Detector with Germanium Tagging system at the National Superconducting Cyclotron Laboratory. The protons and γ rays emitted in the decay were detected simultaneously. Here, a Monte Carlo method was used to model the Doppler broadening of ²⁴Mg γ-ray lines caused by nuclear recoil from proton emission. Shell-model calculations using twomore »« less
