The energy straggling ..cap omega../sup 2/ of 0.5-, 1.0-, 1.5-, and 2.0-MeV ..cap alpha.. particles in thin vapor-deposited films of Ti, Cr, Co, Cu, and Ag onto a thick substrate has been measured to +- 6% by an elastic scattering technique using a magnetic spectrometer. The measurements reveal a linear ..cap omega../sup 2/ versus target thickness dependence and a mild increase with energy for a fixed target thickness. When ..cap omega../sup 2/ is plotted as a function of Z/sub 2/, a decrease in energy straggling with increasing atomic number is observed, although it is considerably higher than predicted by the Bonderup-Hvelplund modification of the Lindhard statistical approach.
