High-spin structures in the neutron-rich {sup 108}Tc nucleus have been reinvestigated by measuring the prompt {gamma}-rays from spontaneous fission of {sup 252}Cf. A previously known collective band has been extended up to higher spin states and a new side band has been identified. These doublet bands are proposed as pseudospin partner bands with configurations {pi}1/2{sup +}[431] x {nu}[312{approx}5/2{sup +},3/2{sup +}], which is a first identification in A{approx}100 region. The particle-rotor model (PRM) was applied to calculate levels and B(M1)/B(E2) ratios of the bands in {sup 108}Tc. The calculated results are in good agreement with the experimental values.
