Darwin fowler method
In statistical mechanics, the Darwin–Fowler method is used for deriving the distribution functions with mean probability. It was developed by Charles Galton Darwin and Ralph H. Fowler in 1922–1923.

WebNov 4, 2010 · This expression is similar to the initial one in the Darwin – Fowler method (Fowler, & Guggenheim, 1939), where it was substantiated as a mathematical device. These contour integrals can be computed by the saddle-point method, when L ¯ ≠ 0. The saddle-points determine the values of χ, ϑ, η. http://www.sbfisica.org.br/bjp/download/v06/v06a30.pdf
