Abstract: (Elsevier)
Studies via the 16 O( 3 He, pγ) 18 F, 14 N(α,γ) 18 F and 17 O(p, γ) 18 F reactions have resulted in new J π assignments for 11 states or negative parity: E x (keV) ( J π ) = 3791(3 − ), 4226(2 (−) ), 4398(4 − ), 4860(1 (−) ), 5502(3 (−) ), 5785(2 − ), 6097(4 − ), 6108(1 (−) , 2 (−) , 3 (−) ), 6241(3 − , T = 1), 6643(2 − , T = 1) and 6878(3 (t-) , 4 − ). The 6241 keV state is probably isospin mixed. New information for 5 states of positive parity has also been obtained: E x (keV) ( J π ) = 3838(2 + ), 4115(3 + ), 4652(4 + , T = 1), 4753((0 + ), T = 1) and 4964(2 + , T = 1). Mean lives, branching and mixing ratios are reported for all states. The results for the negative-parity states are discussed in the framework of the various models available. The states at E x = 1080(0 − ), 2100(2 − ) and 4398(4 − ) keV are interpreted as the first three members of a K π = 0 − rotational band.
