Temperature dependence of decay time and intensity of alpha pulses in pure and thallium-activated cesium iodide

Senftle, F. E.; Martinez, P.; Alekna, V. P.

Abstract:

The intensity and decay time of Po210 ?? particle scintillations produced in pure and thallium-activated cesium iodide have been measured with a fast electronic system as a function of temperature down to 77??K. Three modes of decay due to alpha excitation have been observed for CsI(Tl), and two for CsI. Other than the 7- and 0.55-??sec modes (at room temperature) reported in the literature for CsI(Tl), an additional temperature-independent mode of about 1.3 ??sec has been detected between 77 and 150??K. In CsI a fast temperature-dependent mode of decay (???100 nsec) was observed between 100-200??K in addition to the known principal mode. ?? 1962 The American Institute of Physics.
