$\phi$(1020) Photoproduction on the Neutron

The mechanism of $\phi$ photoproduction on the nucleon is not yet well understood. In order to differentiate between the various mechanisms proposed for $\phi$ photoproduction, data for both differential cross sections and spin observables are needed. All existing experimental data come from $\phi$ photoproduction on the proton, and there is only one published result currently available using a linearly polarized photon beam. There are no experimental results at all for $\phi$ photoproduction on the neutron. Our high-statistics and large-kinematic-coverage g13 experiment, using the CLAS at Jefferson Lab, where both linearly and circularly polarized photons were incident on a deuterium target, can provide such data. We are analyzing these data to extract angular distributions for the $\gamma + n \rightarrow K^+ K^- + n$ reaction channel. An update on the analysis of these data will be presented.
