Abstract 



The deviation effect of spinor mode from the singlemode for a spin1 Bose gas of trapped atoms is studied beyond the mean field theory. Based on the effective Hamiltonian with nondegenerated level of the collective spin states, the splitting level of the system energy due to the deviation effect has been calculated. For the large condensates of (87)Rb and (23)Na with atom number N > 10(5), the splitting fraction of the energy, arising from the magnetization exhibited by the trapped Bose gas, is found to have a typical order of (10(4) similar to 10(8)), decreasing as N(2) for (87)Rb and increasing as N(2) for 23 Na, respectively.
