Measurement of 17 F(d,n) 18 Ne and the impact on the 17 F(p,γ) 18 Ne reaction rate for astrophysics
The 17 F(d,n) 18 Ne reaction is part of the astrophysical “hot CNO” cycles that are important in astrophysical environments like novae. Here, its thermal reaction rate is small owing to the relatively high energy of the resonances and therefore is dominated by direct, non-resonant capture in stellar environments at temperatures below 0.4 GK.

Inelastic Neutron Scattering Study of a Nonmagnetic Collapsed Tetragonal Phase in Nonsuperconducting CaFe2As2: Evidence of the Impact of Spin Fluctuations on Superconductivity in the Iron-Arsenide Compounds
The relationship between antiferromagnetic spin fluctuations and superconductivity has become a central topic of research in studies of superconductivity in the iron pnictides. We present unambiguous evidence of the absence of magnetic fluctuations in the nonsuperconducting collapsed tetragonal phase of CaFe2As2 via inelastic neutron scattering time-of-flight data, which is consistent with the view that spin fluctuations are a necessary ingredient for unconventional superconductivity in the iron pnictides. We demonstrate that the collapsed tetragonal phase of CaFe2As2 is nonmagnetic, and discuss this result in light of recent reports of high-temperature superconductivity in the collapsed tetragonal phase of closely related compounds.
