Abstract

We present electron collision strengths and their thermally averaged values for the 
nebular forbidden lines of the astronomically abundant doubly ionized oxygen ion, 
O2+, in an intermediate coupling scheme using the Breit-Pauli relativistic terms as 
implemented in an R-matrix atomic scattering code. We use several atomic targets 
for the R-matrix scattering calculations including one with 72 atomic terms. We 
also compare with new results obtained using the intermediate coupling frame 
transformation method. We find spectroscopically significant differences against a 
recent Breit-Pauli calculation for the excitation of the [O III] ?4363 transition but 
confirm the results of earlier calculations.
