Poster session, J6 169High-temperature pulsed source of Cd 2 and CdRg molecules insupersonic beamTomasz Urbanczyk 1 , Jaroslaw Koperski 2Smoluchowski Institute of Physics, Jagiellonian University, Krakow, Poland1 tomek.urbanczyk@uj.edu.pl; 2 ufkopers@cyf-kr.edu.plUrbanczyk T.Koperski J.We present an all-metal pulsed source of supersonic molecular beam of Cd 2 and CdRg(Rg=rare gas) van der Waals molecules which operates at temperatures and carrier gasstagnation pressures up to 1000K and 8 bar, respectively.Fig. 1: High-temperature pulsed source: a) cross section, b) 3D view.Scheme of the source is presented in Fig. 1. The source was applied for production andspectroscopy of Cd 2 and CdRg molecules. Simulations of the recorded LIF excitationspectra (Fig. 2) show that the rotational temperature of produced molecules is about 3K.In the future the source will be incorporated into an experiment dedicated to realizationof an entanglement between 111 Cd atoms produced via dissociation of ( 111 Cd) 2molecule. 1 30675 30690 30705 30720 30735 30750 30765aLIF intensity [arb. units]bcdlaser frequency [cm -1 ]Fig. 2: a) and c) LIF excitation spectra of CdAr and Cd 2 recorded usingB 3 1(5 3 P 1 )←X 1 0 + (5 1 S 0 ) and b 3 0 + u (5 3 P 1 )←X 1 0 + g (5 1 S 0 ) transitions, respectively, underdifferent conditions of the detection. b) and d): simulations of the spectra shown in a)and c), respectively.References[1] J.
