In this work, necessary and sufficient conditions for oscillation of solutions of second-order neutral impulsive differential system

\begin{eqnarray*} \{\begin{array}{lcl} \big(r(t)(z'(t))γ\big)' + q(t)xα\big(σ(t)\big)=0, && t≥ t0, t\neq λk, Δ \big(r(λk)(z'(λk))γ\big) + h(λk)xα \big(σ(λk)\big)=0, && k \in \mathbb{N} \end{array} . \end{eqnarray*}

are established, where

$$ z(t)=x(t)+p(t)x\big(τ(t)\big). $$

Under the assumption $\int\big(r(η)\big)-1/α \mathrm{d}η = ∞$, two cases when $γ > α$ and $γ < α$ are considered. The main tool is Lebesgue's Dominated Convergence theorem. Examples are given to illustrate the main results, and state an open problem.
