Abstract

Directional-correlation measurements of γ-rays with protons in the reaction 18O(3He, pγ) 20F through several of the levels of 20F up to 3 MeV in excitation have been made in collinear reaction geometry. With this extension of our earlier work has been combined an extensive review of all available experimental work bearing on each of the levels discussed. The spin and parity assignments ensuing are compatible with earlier publications; usually they are more restricted and in two cases unambiguous: 656 keV, Jπ = 3+, and 2044 keV, Jπ = 2+. Branching ratios for all of the levels in this range have been measured and are reported, as are the multipole mixing ratios deduced for all of the γ-ray transitions studied.
