THE MOSSBAUER EFFECT IN IRON-57 (thesis)
The Mossbauer effect was studied in stainless steel, commercial iron, and pure Fe/sup 57/ at room temperature. The observed result with stainless steel as absorber and Co/sup 57/ impregnated in a stainless steel source was a 34% relative absorption peak of 1.92 x 10/sup -7/ ev half maximum width. Commercial one mil iron foil with a content of 95% silicon oriented natural iron gave an internal magnetic field W-(3.33 plus or minus 0.01) x 10/sup 5/ oersteds. The observed Zeenian spectrum of six double peaks differed from those obtained from pure iron since the overlapping of the peaks broadened the half maximum widths. The average separation of the double peaks was 6.24 x 10/sup -9/ ev. Using Co/sup 57/-in-iron source and an iron absorber (six-line source and six-line absorber) a seven-peak spectrum was obtained with the maximum intensity central peak at the por-nt of zero relative velocity. The elliptical polarization of the Fe/sup 57/ 14-kev gamma radiation was observed, using Co/sup 57/ impregnated in iron as a source (six-line source) which was mounted on a permanent magnet, and using stainless steel as absorber, at theta = 90, 45, and 25 deg , where theta is the angle between the magnetic field and the direction of propagation of the radiation.
