Crystal field (CF) analysis of the energy levels scheme of Cr3+ ion doped in LiAl5O8 spinel is performed. Using the crystal structure data and exchange charge model of CF, the CF parameters were calculated and Cr3+ CF Hamiltonian was diagonalized in the basis set spanned by 120 wave functions of all 8 LS terms of Cr3+ ion. The obtained energy levels and estimated Racah parameters B and C were compared with experimental spectroscopic data for the LiAl5O8:Cr3+ crystal; good agreement has been demonstrated.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
