Abstract

The level structure of $^{18}$ Ne above the $α$ -decay threshold has been studied using the $^{16}$ O( $^{3}$ He, $n$ ) reaction. A coincidence measurement of neutrons and charged particles decaying from populated states in $^{18}$ Ne has been made. Decay branching ratios were measured for six resonances and used to calculate the $^{14}$ O( $α$ , $p$ ) $^{17}$ F reaction rate which is a measure of one of two breakout paths from the hot CNO cycle. The new experimental information combined with previous experimental and theoretical information provides a more accurate calculation of the reaction rate.
