Abstract

A recoil coincidence technique has been applied to measure the [Formula Presented]-decay branching ratios of near-threshold states in [Formula Presented] Populating these states using the [Formula Presented] reaction in inverse kinematics, we detected the recoils and their decay products with 100% geometric efficiency using a magnetic spectrometer. Combining our branching ratio measurements with independent determinations of the radiative widths of these states, we calculate the astrophysical rate of [Formula Presented] Using this reaction rate, we perform hydrodynamic calculations of nova outbursts and conclude that no significant breakout from the hot CNO cycles into the [Formula Presented] process occurs in novae via [Formula Presented].
