Abstract	XPS measurements were made on samples from multi-crystalized ingots grown from Bridgman melts, having a composition corresponding to the formula $CuInSe_{2+x},$ containing added quantities of elemental sodium or $Na_{2}Se.$ Special attention was paid to the XPS peaks Se 3d, Na 1s and O 1s. In particular, two main Se 3d peaks were observed at binding energies of 54.5 and 59 eV. The first of these, previously assigned to ternary $CuInSe_{2},$ increased with etching depth from the ingot surface but was little affected by the presence of Na. However, the second peak only appeared when Na or $Na_{2}Se$ had been added to the melt. The 59 eV peak also increased somewhat with contaminant oxygen content and was assigned tentatively to $Na_{2}SeO_{3}.$
