Mass-attenuation coefficients of beta particles

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1990
Abstract A method to obtain mass-attenuation coefficients of β particles is described. This method is based upon the simulation of β emission by means of the β energy spectrum. The range of the β particle is chosen as random incidence by means of range distribution of monoenergetic electrons which have the same energy as the β particle.

Beta Coefficients for Convertible Bonds

The Journal of Finance, 1975
WHEN THE STANDARD portfolio model is applied to convertible bonds, the changing relationship between the common stock conversion value and the straight bond value give the resulting betas a high degree of non-stationarity. It is the purpose of this note to take the valuation model of Poensgen [2], extend it to include the market portfolio of common ...
