“…These data indicate that the error on stopping power measurements is consistent with the value quoted by Greife et al [22], implying that the error in Ref. [19] is underestimated.…”

“…This was motivated by an analysis of a large set of 20 Ne + H 2 energy loss data taken subsequent to the publication of Ref. [19]. These data indicate that the error on stopping power measurements is consistent with the value quoted by Greife et al [22], implying that the error in Ref.…”

“…20 Ne (p, γ) 21 Na. The references are Tan60 [5], Eng05 [19], and Kei77 [23]. For comparison, the laboratory frame Thomas and Tanner result, ωγ = 1.13 ± 0.07 eV [5], is also displayed by the band across the top of the figure.…”

“…Fig. 2 displays the present result along with that of Thomas and Tanner [5] (in the center of mass); the DRAGON commissioning experiment [19]; and the solid target measurement of Keinonen, Riihonen, and Anttila [23]. For the DRAGON commissioning experiment, we have recalculated the resonance strength using the presently employed stopping power, which has a larger error than the stopping power used originally.…”

Advances in instrumentation for nuclear astrophysics

“…As typical cross sections for capture reaction are sub-mb, a rejection upward of 10 9 is necessary. A number of recoil separators have been installed at various laboratories for the purpose of measuring capture reactions, including the Astrophysics REcoil Separator (ARES) at Louvain la Neuve, 7 the Detector of Recoils and Gammas Of Nuclear reactions (DRAGON) 8 at TRIUMF, the Daresbury Recoil Separator (DRS) at Oak Ridge National Laboratory. 9 These devices have been used to measure a number of astrophysically important reactions, including 19 Ne(p,γ ) 20 Na with ARES, 10 17 F(p,γ ) 18 Ne using the DRS 5 (see Sec.…”
