Abstract

The 6164, 6284, 6310, 6383, 6480, 6777 and 6803 keV states have been studied via the capture reactions 14N(α, γ)18F and 17O(p, γ)18F. These studies yield respective assignments of JπT = 3+(1), 2+(0+1), 3+(0), 2+(0+1), 3+(0), 4+(0) and 1+, 2 or 3+(0). Information on radiative widths, branching and multipole mixing ratios is reported. The 6164 and 6777 keV states are well described theoretically by simple (d52 s12)3+ and (d52 d324+ configurations, respectively. The 2+ states at 6284 and 6383 keV are mixed in isospin. A comparison of the observed properties with the available model calculations is presented for the above states as well as for some low-lying positive-parity states.
