The $^{9}$Be($^{14}$C, $\alpha$$\gamma$) reaction at E$_{Lab}$=30 and 35 MeVwas used to study excited states of $^{19}$O. The Florida State University(FSU) $\gamma$ detector array was used to detect $\gamma$ radiation incoincidence with charged particles detected and identified with a silicon$\Delta$E-E particle telescope. Gamma decays have been observed for the firsttime from six states ranging from 368 to 2147 keV above the neutron separationenergy (S$_{n}$=3962 keV) in $^{19}$O. The $\gamma$ decaying states areinterspersed among states previously observed to decay by neutron emission. Theability of electromagnetic decay to compete successfully with neutron decay isexplained in terms of neutron angular momentum barriers and small spectroscopicfactors implying higher spin and complex structure for these intruder states.These results illustrate the need for complementary experimental approaches tobest illuminate the complete nuclear structure.
