The "missing" 3+ state of Ne18 and explosive F17(p, γ) burning
Wiescher, Görres, and Thielemann suggested that a "missing" Jπ=3+ level in Ne18 should occur at Ex≈4.33 MeV, only ≈410 keV above the F17+p threshold. They noted that this level would provide an s-wave resonance in the F17(p, γ) reaction, greatly increasing its thermonuclear reaction rate....

The "missing" 3+ state of Ne18 and explosive F17(p, γ) burning |
| abstract |
Wiescher, Görres, and Thielemann suggested that a "missing" Jπ=3+ level in Ne18 should occur at Ex≈4.33 MeV, only ≈410 keV above the F17+p threshold. They noted that this level would provide an s-wave resonance in the F17(p, γ) reaction, greatly increasing its thermonuclear reaction rate. This, in turn, would have a pronounced effect on the production of O17 and O18 in explosive stellar environments. We have searched for this level using the O16(He3, n) reaction. High-resolution time-of-flight spectra show that the 3+ level occurs at Ex=4.561±0.009 MeV, ≈230 keV higher than suggested. The astrophysical consequences of this result are discussed. |

They noted that this level would provide an s-wave resonance in the F17(p, γ) reaction, greatly increasing its thermonuclear reaction rate. This, in turn, would have a pronounced effect on the production of O17 and O18 in explosive stellar environments. We have searched for this level using the O16(He3, n) reaction. High-resolution time-of-flight spectra show that the 3+ level occurs at Ex=4.561±0.009 MeV, ≈230 keV higher than suggested. The astrophysical consequences of this result are discussed.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">APS Digital Backfile Archive 1893-2003</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">García, A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Adelberger, E.
