The microscopic cross section may be considered 1/v.

a. The value in the appendix is tat room temperature of T_{o}=293.61° K .The value is 0.0010 b

b. Temperature corrections for 1/v cross sections are given by the expression following Eq. (3.59):

\overline{\sigma}_{a T}(T)=\left(T_{o}/T\right)^{1/2}\overline{\sigma}_{a T}(T_{o})

Since 300 °C = 300 + 273 °K = 573 °K

{\bar{\sigma}}_{aT}(573)=\left(293.6/573\right)^{1/2}0.0010=7.2\cdot10^{-4}   b
