Abstract: The effect of disorder induced by neutron irradiation in a nuclear reactor (thermal neutron fluence

$1\times10^{19}\,$ cm

$^{-2}$ ) on the superconducting transition temperature

$T_c$ and the upper critical field

$H_{c^2}$ of polycrystalline MgB

$_2$ samples was investigated. Despite the appreciable radiation-induced distortions (more than ten displacements per atom), the initial crystal structure (C32) was retained. The temperature

$T_c$ decreased from

$38$ to

$5$ K upon irradiation and was practically completely restored after the subsequent annealing at a temperature of

$700^\circ$ C. A weak change in the

$dH_{c^2}/dT$ derivative upon irradiation is explained by the fact that the irradiated samples are described by the «pure» limit of the theory of disordered superconductors. The suppression of

$T_c$ upon disordering may be due to the isotropization of the originally anisotropic (or multicomponent) superconducting gap or to a decrease in the density of electronic states at the Fermi level.
