Direct measurement of resonance strengths in S 34 (α,γ) Ar 38 at astrophysically relevant energies using the DRAGON recoil separator [PDF]

, 2018
Background: Nucleosynthesis of mid-mass elements is thought to occur under hot and explosive astrophysical conditions. Radiative α capture on S34 has been shown to impact nucleosynthesis in several such conditions, including core and shell oxygen burning,

Probing astrophysically important states in the ²⁶Mg nucleus to study neutron sources for the s process [PDF]

, 2015
Background: The ²²Ne(α,n) ²⁵Mg reaction is the dominant neutron source for the slow neutron capture process (s process) in massive stars, and contributes, together with C¹³(α,n)O¹⁶, to the production of neutrons for the s process in asymptotic giant ...

Muon-Induced Background Study for an Argon-Based Long Baseline Neutrino Experiment

, 2012
We evaluated rates of transversing muons, muon-induced fast neutrons, and production of $^{40}$Cl and other cosmogenically produced nuclei that pose as potential sources of background to the physics program proposed for an argon-based long baseline ...

The impact of individual nuclear properties on $r$-process nucleosynthesis

, 2015
The astrophysical rapid neutron capture process or `$r$ process' of nucleosynthesis is believed to be responsible for the production of approximately half the heavy element abundances found in nature. This multifaceted problem remains one of the greatest

Optimization of "Glucose ¹¹C" pharmaceutical production on the beam of an electron accelerator [PDF]

, 2021
The process of “Glucose ¹¹C” pharmaceutical production by means of a photonuclear reaction ¹²C(γ, n)¹¹C is considered. The parameters of bremsstrahlung and electron beam scattered in the converter are investigated and optimized.

Formation of mixed X,n-radiation field at an electron accelerator [PDF]

, 2022
For conducting photonuclear programs with the use of a high-intensity photon source the latter is ordinary obtained by transformation of an electron beam into X-ray radiation. Such a process is performed using an intermediate target-converter maid from a
