Th study of polarizd rflctivity proprtis of th plasma was accomplishd with plasma dsity =.7 g/cm 3, prssurs up to P ~ 8 GPa ad tmpraturs up to T ~ 3 4 K udr coditios with strog Coulomb itractio th oidality paramtr up to Г ~.. Th itgratio of Mawll quatios has b basd o a itrpolatio formula for dc coductivity, obtaid from a systmatic quatum statistical tratmt of diffrt limitig cass. To itrprt corrctly th rsults of rflctivity masurmts it is cssary to kow paramtrs of a trasitiv plasma layr.
