C. Bargholtz et al., Using a CdTe detector for Te-125 Mossbauer Spectroscopy: Application to the f-factor in Mg3TeO6, NUCL INST B, 170(1-2), 2000, pp. 239-244
An apparatus for Mossbauer spectroscopy has been developed with a cadmium t
elluride (CdTe) gamma-ray detector. Complete data regarding gamma-ray energ
y, source velocity, temperature and real time are stored for off-line analy
sis. The apparatus has been used to study the spectrum of Te-125 in Mg3TeO6
at room temperature. The 35.5 keV transition of Te-125 in Mg3TeO6 was foun
d to have a recoil-free fraction f = 0.392(5) corresponding to a Debye temp
erature theta = 352(3) K. (C) 2000 Elsevier Science B.V. All rights reserve
