Popis:	The picture of magnetic level splitting for the 1s7h configuration of helium is calculated with the fine-structure parameters obtained by the semiempirical method. Only the terms linear in the magnetic field strength are taken into account in the matrix elements of the energy operator of interaction of the atom with the magnetic field. In the region of magnetic field strength up to 30 Oe, 4 anticrossings and 73 crossings of the magnetic sublevels were found. Based on the pure $$j_1 j_2 m_{j_1 } m_{j_2 } $$ coupling between the electron angular momenta, the results obtained are compared to the results calculated using the jj and model $$m_{l_1 } m_{l_2 } m_{s_1 } m_{s_2 } $$ representations.
