INTERNAL BREMSSTRAHLUNG FROM P$sup 32$ AND Y$sup 9$$sup 0$
The internal bremsstrahlung spectra of the allowed beta emitter P/sup 32/ and the first forbidden beta emiter Y/ sup 90/ were studied using a scintillation spectrometer and compared with available calculations. The experimental spectrum of P/sup 32/ does not agree exactly with the Knipp, et al., theory for allowed beta transitions. The deviations are not large but are significant and can be explained by the Coulomb corrections proposed by Lewis and Ford. The observed spectrum of Y/sup 90/ disagrees with the extension of the Knipp, et al, theory for first forbidden beta transitions with tensor interactions. The Coulomb correction is inadequate to account for the deviation. The observed photon excess may be arising from detour transitions; an assumption supported by calculations of Lewis and Ford. (uth)
