Abstract New results on the high resolution spectrum of ArI in the 3s-subshell excitation region are reported. The spectra are recorded in the second order of a 3-meter vacuum spectrograph and synchrotron radiation as the background source of continuum. The transitions: $$\begin{array}{*{20}c} {3s^2 3p^6 {}^1S_0 \to 3s({}^2S_{{1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-\nulldelimiterspace} 2}} )3p^6 np} & {{}^1P_1 (4 \leqq n \leqq 25)} \\ \end{array} $$ have been extended to highern-values and more accurate level positions and binding energy of the 3s-subshell is achieved from the series limit. The spectrum has been analysed within the framework of non-relativistic Hartree-Fock and relativistic Hartree-Fock calculations. Intensity anomalies aroundn=9 have been atributed to an additional level arising from doubly excited state 3s 23p 44s4p.
