| Abstract: | Delayed spectra of foil-excited fast Cu ions have been studied to find a number of 3s3p4, 3 s2 3 p2 3 d and 3s3p33d levels in the P-like ion Cu14+ (spectrum Cu XV). Among these are 3 s 3 p3 3 d 6 D levels, which have never been observed before, although they are the lowest excited states that have the same parity as the ground configuration. The investigation combined theory and experiment. The calculations used the Cowan code with semi-empirically scaled parameters and extensive MCDF computations.
