【 摘 要 】
Let ð‘‹ be a closed, simply-connected, smooth, spin 4-manifold whose intersection form is isomorphic to $n(-E_8)oplus mH$, where ð» is the hyperbolic form. In this paper, we prove that for ð‘› such that $n≡ 2mathrm{mod} 4$, there exists a locally linear pseudofree $mathbb{Z}_2$-action on ð‘‹ which is nonsmoothable with respect to any possible smooth structure on ð‘‹.
