Within a transport code of BUU type the production of φ mesons in the reactions Ni + Ni at 1.93 A GeV and Ru + Ru at 1.69 A GeV is studied. New elementary reaction channels ρN(Δ) → φN and πN(1520) → φN are included. In spite of a substantial increase of the φ multiplicities by these channels the results stay below the tentative numbers extracted from experimental data.
