Abstract:
A method for efficiently determining a Fermi-Dirac integral G(Z) comprising:reducing said Fermi-Dirac integral to first G1(Z) and second G2(z) terms, said first term G1(Z) comprising a Fermi-Dirac integral of order 1/2; ##EQU22## and said second term G2(Z) comprising a Fermi-Dirac integral of a periodic function which includes a summation of terms which converges as: ##EQU23## digitally computing a value for said reduced first term from a lookup table for the values Z over the integral 0 to infinity;digitally computing a value for said second term G2(Z) for values of Z over the integral 0 to infinity; andcombining with said digital computer the results of computing said first and second terms for each value of Z.
