Laser excitation and resolved emission spectra of supersonically cooled aluminum dimer

Potential Functions of Al2 by the Relativistic Fock-Space Coupled Cluster Method

“…The equations for the (m, n) sector involve only S elements from sectors (k, l) with k ≤ m and l ≤ n, so that the very large system of coupled nonlinear equations is separated into smaller subsystems, which are solved consecutively: first, the equations for S (0,0) are iterated to convergence; the S (1,0) (or S (0,1) ) equations are then solved using the known S (0,0) , and so on. This separation, which does not involve any approximation, reduces the computational effort significantly.…”

“…The 3p valence electrons can go into either pσ g or pπ u bonding orbitals, yielding a number of close-lying potential curves. The nature of the ground state was not clear for many years (references to early work may be found in [1]); more recently, both theoretical [2,3] and experimental [1,4] studies identified the ground state as σ g π u X 3 Π u , followed closely by π 2 u A 3 Σ − g . The adiabatic energy separation T e of the two states has not been determined experimentally; theoretical predictions [2,3] are about 200 cm −1 .…”

Nonadiabatic Predissociation Studies of the (1-3)3Πg System of Al2 by Means of a Complex Rotated Finite Element Method

“…[9]. The rotational contribution to U (d) (R) is described in terms of quantum numbers for the total angular momentum J , and the electronic angular momentum ,…”

“…The Al 2 dimer has been the subject of considerable interest the past 10 years, both theoretically (2-7) and experimentally (8)(9)(10)(11)(12). Among several spectroscopic problems in Al 2 , one of the most interesting is the predissociation mechanism in the (1-3) 3 g manifold.…”

Apparatus and techniques for the investigation of methods of generating molecular beams

“…Очевидно, что в связи с резким ростом интереса к строению кластеров (например, [87]) устройства, подобные описанным выше, будут интенсивно развиваться.…”
