Abstract: We establish the slice-ribbon conjecture for a family $ \mathscr{P}$ of Montesinos knots by means of Donaldson's theorem on the intersection forms of definite $ 4$-manifolds. The $ 4$-manifolds that we consider are obtained by plumbing disc bundles over $ S^2$ according to a star-shaped negative-weighted graph with $ 3$ legs such that: i) the central vertex has weight less than or equal to $ - 3$; ii)  $ -$   total weight$ - 3 \char93 $   vertices$ <-1$. The Seifert spaces which bound these $ 4$-dimensional plumbing manifolds are the double covers of $ S^3$ branched along the Montesinos knots in the family $ \mathscr{P}$.
