Abstract
An original technique for describing excited states of electrons in crystal structure has been considered by an example of lithium. It is shown that the electron spectrum in lithium changes only slightly at large values of lattice parameter (up to 8.77 Bohr radii). The lifetimes of excited electrons of external s and p states differ significantly at lattice parameters d < 8.77 Bohr radii. A metastable crystalline state of bcc lithium is found, which barely depends on the excitation power at a lattice constant equal to 6.55 Bohr radii, corresponding to the bcc lattice constant of lithium in the ground state.
