It is shown that in the decays Bc(2P)→Bc* γ, Bc(3P)→Bc* γ and Bc(2S)→Bc*+π+π− followed by the decay Bc*→Bc+γ(soft) the loss of the soft photon γ(soft) do not wash out peaks from the initial excitations. The relative yields of Bc, 2P-wave, and 3P-wave states of Bc meson at LHC are estimated as function of transverse energy of emitted photon γhard. It is pointed out, that the decays Bc(2S)→Bc(Bc*)+π+π− could provide a new information about a σ resonance nature.
