Spin-flip transitions inO16andO18excited by inelastic proton scattering

Inelastic proton scattering at forward angles has been carried out on ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ and ${}_{}{}^{18}{}_{}{}^{}\mathrm{O}$ at a bombarding energy of 201 MeV. The (p,p’) spin-flip transitions to $1^{+}$ and $2^{\mathrm{-}}$ states are compared with (e,e’), (p,γ), and charge exchange data, and with microscopic distorted-wave Born approximation calculations using shell model wave functions. The ratios of orbital to spin contributions are deduced for the known $1^{+}$ states in ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$.
