The inner bremsstrahlung spectrum associated with the nonunique first-forbidden ..beta.. decay of /sup 147/Pm was measured employing the magnetic deflection method with a 4.5 x 5.1 cm/sup 2/ NaI(Tl) scintillation spectrometer in the energy region 30--200 keV. The contribution due to the 121 keV source gamma ray line was subtracted by normalizing its peak with that of the 122 keV /sup 57/Co gamma ray pulse height distribution recorded in the same experimental setup. The raw spectrum was unfolded following Liden and Starfelt and compared with theoretical spectral distributions. The measured spectral distribution does not match any of the theories in any part of the investigated energy region.
