Abstract
Wiescher, Görres, and Thielemann suggested that a "missing" level in should occur at MeV, only ≈410 keV above the + threshold. They noted that this level would provide an -wave resonance in the reaction, greatly increasing its thermonuclear reaction rate. This, in turn, would have a pronounced effect on the production of and in explosive stellar environments. We have searched for this level using the reaction. High-resolution time-of-flight spectra show that the level occurs at MeV, ≈230 keV higher than suggested. The astrophysical consequences of this result are discussed.
