Abstract

The bound states of N15 have been studied by the N14(d,p) reaction. Absolute differential cross sections were measured at Ed=3 MeV for the 9.05-, 9.152 + 9.155-, 9.22-, 9.76-, and 10.07-MeV states and at Ed=3.6 MeV for the 9.76-, 9.83-, 9.93-, 10.07-, and 10.45-MeV states in N15. The target was natural nitrogen confined in a differentially pumped gas target. Distorted-wave Born-approximation analysis and Hauser-Feshbach calculations indicate that ln=1 is involved in the formation of the 9.22-, 9.76-, and probably 10.45-MeV states, whereas ln=2 transfer is associated with the 9.155-MeV level. An ln=0 transfer was discerned for the angular distribution associated with the 9.05-MeV state and ln=0+2 for the angular distribution associated with the 10.07-MeV and probably the 9.93-MeV N15 state. Spectroscopic factors have been obtained. The correspondence between mirror levels in N15 and O15 and those predicted within the framework of the weak-coupling model is discussed.
