    "abstract": "Phi meson production in pion-baryon and baryon-baryon interactions near the\nproduction threshold is studied in a boson-exchange model. Parameters in this\nmodel are either taken from the Bonn model for the nucleon-nucleon potential or\ndetermined from the measured phi meson decay width and the experimental data\nfor the reactions $\\pi^-p\\arr \\phi n$ and $pp\\arr pp\\phi$. The isospin-averaged\ncross sections for the reactions $\\pi N\\arr \\phi N$, $\\pi \\Delta \\arr \\phi N$,\n$NN\\arr NN\\phi$, which are needed in transport models to study phi meson\nproduction in heavy-ion collisions at subthreshold energies, have been\nevaluated. For the reactions $N\\Delta\\arr NN\\phi$ and $\\Delta\\Delta\\arr\nNN\\phi$, which become singular when the exchanged pion is on-shell, the Peierls\nmethod is used to calculate their cross sections. We find that the cross\nsection for the reaction $\\pi N\\arr\\phi N$ is much larger than the other cross\nsections.",
