Spectroscopic study of the 22Σ+ and the 42Σ+ excited states of LiCa

Alexander A. Stein, Milena Ivanova, A. Pashov, H. Knöckel et autres

The 2(2)Σ(+) and 4(2)Σ(+) excited states of (7)Li(40)Ca have been studied by high resolution Fourier-transform spectroscopy. The data on the lower state, 2(2)Σ(+), were obtained by analyzing the rotationally resolved spectra of the thermal emission of LiCa in the 2(2)Σ(+) → X(2)Σ(+) …

The B1Π and D1Π states of LiRb

Milena Ivanova, Alexander A. Stein, A. Pashov, H. Knöckel et autres

We studied the molecule LiRb in the gas phase with high resolution by Fourier-transform spectroscopy of laser induced fluorescence. The spectra were assigned to transitions between the ground state X(1)Σ(+) and B(1)Π or D(1)Π states and showed perturbations. For levels with e …

The X2Σ+ state of LiCa studied by Fourier-transform spectroscopy

Milena Ivanova, Alexander A. Stein, A. Pashov, A. V. Stolyarov et autres

The paper reports on a successful observation of high resolution Fourier transform spectra of LiCa. The fine structure of the ground state was observed and attributed to effective spin-rotation interaction. The experimental observations are described by two models using potential energy curves. …

The X 1Σ+ state of LiRb studied by Fourier-transform spectroscopy

Milena Ivanova, Alexander A. Stein, A. Pashov, H. Knöckel et autres

We report on the first experimental observation of the ground electronic state of the LiRb molecule at high resolution. A large body of experimental data was collected which led to an accurate potential energy curve for this state. Transitions to the lowest …

Production of /sup 8/Li/sub 3/ fragments in interaction of 250-GeV protons with heavy emulsion nuclei

Milena Ivanova, Vladimir Kurbatov, V.M. Sidorov

In scanning nuclear emulsions we found about 600 cases of production of /sup 8/Li/sub 3/ fragments in interaction of 250-GeV protons with heavy emulsion nuclei. Angular and energy spectra of the /sup 8/Li/sub 3/ fragments were obtained. An estimate is given of …
