HARTREE-FOCK STUDY OF MOLECULES IN VERY INTENSE MAGNETIC-FIELDS

We investigate the stability of homonuclear diatomic molecules from H-2 UP to C-2 and of the finite chains H-n (n less than or equal to 5) and He-n (n less than or equal to 4) immersed in very intense magnetic fields (B approximate to 10(8) T). The atomic and molecular total energies are calculated within the one-dimensional Hartree-Fock approximation, using a Lagrange basis set associated with a Cartesian mesh. The stability of the molecules decreases beyond Lit although all the studied molecules are found stable. The energy per atom of H and He finite chains stabilizes already for the small chain sizes that we have investigated.
