“…In agreement with the previous ( He, p) reaction [4], the angular distribution to the 3.680 MeU level is well fitted by the L =4 transfer (Fig. 4).…”

“…The 3.587 MeV level, not included in paper I, is strongly excited in the ( He, p) reaction with angular distribution well fitted by the L =2 DWBA cure (Fig. 2) and may perhaps be a good candidate for the third 2+ (sd) shell model state, but this J value will not be consistent with the L =2+4 transition found the previous ( He, p) work [4]. The J value of the level is given as (1, 2)+ in the ' F(n, y ) F reaction [16] and adopted [13].…”

“…It turned out that an overall good description of the angular distributions is given by the combinations H4-P3 and HS-P4, containing the spin-orbit potential in both the entrance and exit channels. These combinations were also used by Crozier and Fortune [4) and in paper I for the ' 0( He, p) reaction at 18 MeV. These were used in the present work and are shown in Table II.…”

“…A more detailed investigation of the reaction is carried out in the present work; energy levels in F are obtained up to E -8.5 MeV and the angular distributions are measured for many of the levels of either parity up to E"-6.2 MeV. The ' 0( He, p ) F reaction was previously studied by Crozier and Fortune [4] at 18 MeV covering an excitation energy up to E"-3. 8 MeV.…”

Studies of X-ray burst reactions with radioactive ion beams from RESOLUT

“…The rates of many of these reactions are purely theoretical or have large uncertainties due to experimental challenges in studying short-lived nuclei that hinder our understanding of X-ray bursts. e-mail: blackmon@lsu.edu Some of the important reactions in X-ray bursts are those that involve breakout of the hot-CNO cycle, either through the 17 F(p,γ) 18 Ne(α,p) 21 Na or 15 O(α,γ) 19 Ne(p,γ) 20 Na reaction sequences. We measured the 17 F(d,n) 18 Ne and 19 Ne(d,n) 20 Na reactions to improve our understanding of the 17 F(p,γ) 18 Ne and 19 Ne(p,γ) 20 Na capture reactions, respectively, that are important in breakout from the hot-CNO cycle.…”
