The radiative and Auger rates are calculated for doubly excited intersh-ell states of Ar16+. We adopt the conventional infiguration interraction CI app-roach, bul each state is labelled using the n(K,T)NA2s+1Lπ designation. lt is shown that, to intrashell states which all have A = +1, these states decay prima-rily by auger process and radiative decay contributed significantly only for the hi-ghest states within a given manifoid, but to intershell states the Auger widths are much smaller tor A =-1 and A = 0 states. For these states the flourescence yield may become non-negligible. The approximate selection rule v=- 0,±1 for radiative decay holds for these states as well.
