Experimental values of internal-conversion coefficients of nuclear transitions: total and K-shell coefficients and L-subshell coefficient ratios

A tabulation is presented of experimentally measured values of internal-conversion coefficients for the K-shell, α_K, L-subshells (mostly ratios only, L₁:L₂:L₃), and for all shells, α_total. Results reported prior to November 1965, whose uncertainties are ≦ 25%, are listed and compared with theoretical values. Transition energies and spins an parities of initial and final levels, when known, are included. The theoretical values were obtained from computer interpolation, and in some cases extrapolation, of the tables of Sliv and Band. A brief discussion of the methods of measuring conversion coefficients is given.
