Using a flat T1AP crystal speotrograph,we have recorded photographically the X-ray spctrum of laser-produced copper plasma in the range of 8-14A. According to Moseley rule combined with the method of rederiving wavelength from some known transitions, we have classified about one hundred new spectra of CuXXII, which belong to the transitions 2P338 → 2822P4 and 2P33D → 2S22P4. The uncertainty of the calculated result is less than 5 mA. Compared with the experimental one.
