Highlighted theoretical analyses:2011Fo02:Reanalyzed data on^{15}C levels populated in^{13}C(t,p)^{15}C and interpreted results to revise predictions on^{15}F levels.2010Mu03:Parameters of the lowest Jπ=1/2^{+}and 5/2^{+}states were analyzed via the S-matrix pole method.2015Gr04:Analysis, which focused on^{16}Ne, found the^{15}F ground state should lie near E_{res}(p+^{14}O)=1.39 to 1.42 MeV.2006Ca08, 2015Fr04:Analyzed the^{14}C+n system and then used multichannel algebraic scattering theory to predict resonances in the mirror^{15}F nucleus. See also 2007Ca31.2005Ba73:α microscopic cluster model was developed that was tuned to the^{14}C+n system and used to predict the^{14}O+p scattering reaction and^{15}F resonances. Results are compared and found in agreement with an R-matrix analysis of experimental observations.2005Fo10:The lowest t=3/2 and Jπ=1/2^{+}and 5/2^{+}states of the α=15 quartet are analyzed in a (0^{+}2)h|w shell model.2006Fo16:The definition of resonance energy is explored by considering three different parameters that may define the position: "(a) the energy at which the appropriate cross section peaks, (b) the energy at which the nuclear phase shift has the value δ=π/2, and (c) the energy at which the magnitude of the internal wave function or the derivative of the phase shift dδ/dE is a maximum. " Then, discussion on various α=15 and 16 states and analysis of the IMME mass relation are used to constrain predicted values for poorly known^{15}O,^{15}F and^{16}F states.General theoretical analyses:Other theoretical analyses relevant to

^{15}F include general calculations on mass and structure properties in (1978Gu10,1993Po11,2008Qi04,2013Ci04). More detailed analyses considering pairs of mirror nuclides, Coulomb shifts, Thomas-Ehrman shifts and other detailed relationships are found in (1988Co15,1995Fo18,1997Gr18,1999Og11,1999Ts06,2013Fo22).Other experimental results:^{15}F is not strongly populated in^{12}C(^{3}He,π^{-}) reactions at E(^{3}He)=283 MeV (1986Mi25) or 235 MeV (1984Bi08).
