Abstract

The [Formula Presented] reaction is one of two routes for breakout from the hot CNO cycles into the [Formula Presented] process in accreting neutron stars. Its astrophysical rate depends critically on the decay properties of excited states in [Formula Presented] lying just above the [Formula Presented] threshold. We have measured the [Formula Presented]-decay branching ratios for these states using the [Formula Presented] reaction at 43 MeV/nucleon. Combining our measurements with previous determinations of the radiative widths of these states, we conclude that no significant breakout from the hot CNO cycle into the [Formula Presented] process in novas is possible via [Formula Presented] assuming that current models accurately represent their temperature and density conditions.
