摘要：

We report on the observation of a gerade Rydberg electronic energy state of Cd-2 van der Waals (vdW) complex vibrationally cooled in a free-jet expansion beam. Cd-2 in the beam were excited from the x(l)0(g)(+)(5(1)S(0)) ground via the b(3)0(u)(+)(5(3)P(1)) intermediate to the final gerade state using optical-optical double resonance (OODR) method. A pronounced vibrational progression with partly resolved isotopologue components was recorded and analyzed. The analysis of isotopic separation indicated the excitation to high vibrational levels (upsilon' approximate to 50). A comparison with the result of ab initio calculations reveals, that Cd-2 was most probably excited to the (3)1(g)-state correlating with the 6(3)S(1) atomic asymptote. (C) 2021 Elsevier B.V.
