ResumoThe internal bremsstrahlung spectra from the $\ensuremath{\beta}$ decay of $^{185}\mathrm{W}$ and $^{32}\mathrm{P}$ were measured using a NaI(T1) scintillation spectrometer with a standard geometrical arrangement. After making all the necessary corrections the experimental results are compared with the allowed theory of Knipp, Uhlenbeck, and Bloch (KUB theory) and also with the Coulomb corrected theories of Lewis, Ford, and Nilsson. In the case of $^{185}\mathrm{W}$ it is found that from 78 to 200 keV the experimental distribution is in good agreement with the KUB theory, whereas beyond 200 keV and below 78 keV the experimental points are far above even the highest Coulomb corrected theoretical distribution of Nilsson. The internal bremsstrahlung from this isotope has not been previously investigated. In the case of $^{32}\mathrm{P}$ the experimental relative intensity spectrum is compared with the KUB theory and also with the Coulomb corrected theory of Lewis and Ford. Fairly good agreement is obtained from 30 to 200 keV with the KUB theory but in the energy region from 200 to 900 keV, the experimental results deviate positively from both the KUB and Lewis and Ford theories. The experimental excess over the Lewis and Ford theory is 15% on the average.RADIOACTIVITY $^{185}\mathrm{W}$, $^{32}\mathrm{P}$; measured internal bremsstrahlung spectrum.
