Shake-up and shake-off spectra in the electron capture decay of atomic Be
Mauro Guerra, Inwook Kim, Stephan Friedrich +33
The most stringent laboratory-based experimental limits on the existence of sub-MeV sterile neutrinos are currently set by decay spectroscopy of radioactive Be embedded into su…
Aluminum-Based Superconducting Tunnel Junction Sensors for Nuclear Recoil Spectroscopy
Spencer L. Fretwell, Connor Bray, Inwook Kim +31
The BeEST experiment is searching for sub-MeV sterile neutrinos by measuring nuclear recoil energies from the decay of Be implanted into superconducting tunnel junction (STJ) s…
High-Precision Excited-State Nuclear Recoil Spectroscopy with Superconducting Sensors
C. Bray, S. Fretwell, L. A. Zepeda-Ruiz +30
Superconducting sensors doped with rare isotopes have recently demonstrated powerful sensing performance for sub-keV radiation from nuclear decay. Here, we report the first high-re…
The Data Acquisition System for Phase-III of the BeEST Experiment
C. Bray, S. Fretwell, I. Kim +27
The BeEST experiment is a precision laboratory search for physics beyond the standard model that measures the electron capture decay of Be implanted into superconducting tunnel…
Elastic scattering of 3He+4He with SONIK
S. N. Paneru, C. R. Brune, D. Connolly +22
Measurements of the elastic scattering cross section of 3He and 4He are important in order to improve constraints on theoretical models of 4He(3He,g)7Be, a key reaction in Big Bang…
First application of Markov Chain Monte Carlo-based Bayesian data analysis to the Doppler-Shift Attenuation Method
L. J. Sun, C. Fry, B. Davids +31
Motivated primarily by the large uncertainties in the thermonuclear rate of the PS reaction that limit our understanding of classical novae, we carried out lifet…
Limits on the Existence of sub-MeV Sterile Neutrinos from the Decay of Be in Superconducting Quantum Sensors
S. Friedrich, G. B. Kim, C. Bray +14
Sterile neutrinos are natural extensions to the standard model of particle physics and provide a possible portal to the dark sector. We report a new search for the existence of sub…
Initial operation of the recoil mass spectrometer EMMA at the ISAC-II facility of TRIUMF
B. Davids, M. Williams, N. E. Esker +8
The Electromagnetic Mass Analyser (EMMA) is a new vacuum-mode recoil mass spectrometer currently undergoing the final stages of commissioning at the ISAC-II facility of TRIUMF. EMM…
Measurement of Lifetimes in 23Mg
O. S. Kirsebom, P. Bender, A. Cheeseman +22
Several lifetimes in 23Mg have been determined for the first time using the Doppler-shift attenuation method. A Monte Carlo simulation code has been written to model the gamma-ray…
Measurement of the 18Ne(a,p_0)21Na reaction cross section in the burning energy region for X-ray bursts
P. J. C. Salter, M. Aliotta, T. Davinson +14
The 18Ne(a,p)21Na reaction provides one of the main HCNO-breakout routes into the rp-process in X-ray bursts. The 18Ne(a,p_0)21Na reaction cross section has been determined for the…
