摘要：

The Ar2+(3s(2)3p(3)nl) satellite states between 73 and 85 eV have been observed directly by threshold photoelectrons coincidence (TPEsCO) spectroscopy. The present study extends the previous observations of these states by optical emission spectroscopies to the region close to the Ar3+ ionization. Different features have been discerned in the TPESCO spectrum. A preliminary assignment of these features using the Rydberg formula and values of the quantum defect that are deduced from lower-lying states is proposed.
