 WORK OF EXTRACTION OF BETA PARTICLES 



(After Bohr-Coster. Taken from Kovarik, McKeehan, Nat. Res. Council Bull. 51, 1929.) 



Works of extraction Vi in volts X 10 5 ; Vi = E{T/R) ; they have been interpolated 

 assuming linear-variation of (T/R)i with c in values given. In computing Vi, logio 

 £ = 6.13129 — 10; values not depending on interpolation italicized. M values, average 

 of Mi and Mv ; to get Mi add, Mv, subtract correction term. Similarly with N, mean of 

 Ni and Nvn ; O, mean of Oi and Ov.
