6.In the present paper, the spherical tensor formalism of the fine structure Hamiltonian for multi-electron atoms is applied to deduce the matrix elements of the spin-spin interaction operator of helium in the LSJM scheme. Based on the result, the fine structure parameter of the spin-spin interaction in helium is derived theoretically. As an example, we calculate concretely the fine structure parameter of (n_1s)(n_2p) configuration of helium atom.

It is found that the-room-temperature radiation down the neck is a dominating factor. It determines the vertical temperature profiles in the 20-30cm range (60-280 K) from the top of the dewar and about 85-95% of the total heat flux into the liquid helium.
