Atomic stopping-power problems encountered in measurements of nuclear γ-ray lifetimes by the Doppler-shift-attenuation method

The measurement of the lifetimes of excited nuclear states

“…Northcliffe and Schilling (1970) have compiled a semi-empirical table of stopping powers for heavy ions. This table was based on measured proton stopping powers with assumption of smooth variations between the points measured for different stopping 28 P J Nolan and J F Sharpey-Schafer C 0 were determined by Broude et al (1972), those in the lower diagram (b) are from a recalculation using the formalism described by Latta and Scanlon (1976). The data are presented in terms of the atomic number 22 and the chemical group of the stopping material (from Latta and Scanlon 1976).…”
