Abstract : The low-spin structure of one-proton, one-neutron $^{210}$Bi nucleus was investigated in cold-neutron capture reaction on
$^{209}$Bi. The $\gamma$-coincidence measurements were performed with use of EXILL array consisted of 16 HPGe detectors. The experimental
results were compared to shell-model calculations involving valence particles excitations. The $^{210}$Bi nucleus offers the potential
to test the effective proton-neutron interactions because most of the states should arise from the proton-neutron excitations. Additionally,
it was discovered that a few states should come from the couplings of valence particles to the $3^-$ octupole vibration in
$^{208}$Pb which provides also the possibility of testing the calculations involving the core excitations.
