There's a very good book by A. Cyganov, about Quantum Mechanics in Maple, unfortunately it is only in Russian. It's explained how to work with bra and ket vectors and non-commutative operators. If you wish I could send you the code, also I'm interested if you have succeeded yourself, so we could compare. But the book was written in the time of Maple 6 and much water has flowed under the bridge since then, doew anyone know if in Maple 10 there's a package for such calculations?

Thanks for your reply. I can't see any font like Cyrillic in the font list. But in Tools>Options>General>Encoding I can change to Cyrrilic, after that the inputs works (only in the standard interfase). Yes, the font used is Times New Roman CYR, maybe it's possible to copy the font file from Windows somehow? In fact, it's a Maple textbook with examples within it, that's why I need to read it. I uploaded the file with one chapter from the book.
