Constraining the Synthesis of the Lightest p Nucleus 74Se
A. Tsantiri, A. Spyrou, E. C. Good +42
We provide the first experimental cross section of the reaction to constrain one of the main destruction mechanisms of the p nucleus $^{74}\text…
New approach for the quantification of uncertainties in reaction modeling via data-driven multi-objective optimization
N. Dimitrakopoulos, G. Perdikakis, F. Montes +5
We introduce a new multi-objective optimization approach to determine uncertainty-quantified nuclear reaction parameters in the Hauser-Feshbach framework. By simultaneously account…
Machine-Learning-Enabled Measurements of Astrophysical (p,n) Reactions with the SECAR Recoil Separator
P. Tsintari, N. Dimitrakopoulos, R. Garg +29
The synthesis of heavy elements in supernovae is affected by low-energy (n,p) and (p,n) reactions on unstable nuclei, yet experimental data on such reaction rates are scarce. The S…
Measurement of Charge State Distributions using a Scintillation Screen
C. Marshall, Z. Meisel, F. Montes +12
Absolute cross sections measured using electromagnetic devices to separate and detect heavy recoiling ions need to be corrected for charge state fractions. Accurate prediction of c…
Implementation and validation of realistic (n,x) reaction yields in GEANT4 utilizing a detailed evaluated nuclear reaction library below 20 MeV
P. Tsintari, G. Perdikakis, H. Y. Lee +5
Neutron-induced reactions with charged particle emission play an important role in a variety of research fields ranging from fundamental nuclear physics and nuclear astrophysics to…

Propagation of Hauser-Feshbach uncertainty estimates to r-process nucleosynthesis: Benchmark of statistical property models for neutron rich nuclei far from stability
S. Nikas, G. Perdikakis, M. Beard +3
Multimessenger observations of the neutron star merger event GW170817 have re-energized the debate over the astrophysical origins of the most massive elements via the r-process nuc…
A technique for the study of (p,n) reactions with unstable isotopes at energies relevant to astrophysics
P. Gastis, G. Perdikakis, G. P. A. Berg +20
We have developed and tested an experimental technique for the measurement of low-energy (p,n) reactions in inverse kinematics relevant to nuclear astrophysics. The proposed setup…
Constraining the destruction rate of K in stellar nucleosynthesis through the study of the Ar(p,n)K reaction
P. Gastis, G. Perdikakis, J. Dissanayake +13
40K plays a significant role in the radiogenic heating of earth-like exoplanets, which can affect the development of a habitable environment on their surfaces. The initial amount o…
Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
