  The $\mathbb{Z}/2\mathbb{Z}$--graded intertwining operators are introduced.
We study these operators in the case of ``degenerate'' N=1 minimal models, with
the central charge $c=3/2$. The corresponding fusion ring is isomorphic to the
Grothendieck ring for the Lie superalgebra ${\mathfrak osp}(1|2)$. We also
discus multiplicity--2 fusion rules and logarithmic intertwiners.
