Abstract：
During the bombardment of 14.8MeV neutron on natural wolfram samples a γ-ray with energy 291.7keV and halflife 5.17±0.03 sec is observed. From the experimental facts it is assumed that in addition to the two well known transition branches from the decay of 5.2 sec isomer in ¹³⁸W there exists another 11/2 ⁺11/2[615]→5/2 ^－3/2[512] isomeric ( E3) transition. The hindrance factor of this new transition is calculated. It is well cosistent with the general empirical rule of k ^－forbidden isomeric transition.
