Abstract

We report the observation of collision-induced spectra of calcium dimer in the 680-692 nm region. The spectra were recorded after resonant laser excitation of 4s4p SP1 state of atomic calcium. Here the upper state a 32,t is populated through collisions. The same spectra were reproduced in a low-current glow discharge in calcium vapor. The assignment of the observed spectral lines was earned out by applying the Dunham-type analysis and the spectra were assigned to the a 32,t -X12S+ transition of Ca2. The existence of a 3Z+ state with vw = 13850 ± 1 cm"1 and u>e-37.6cm-l is confirmed.
