Transport properties of dilute monatomic gases depend on the two body atom-atom interaction potential. When two ground state (4S) nitrogen atoms interact, they can follow any of four potential energy curves corresponding to the N2 molecule; the X 1Σ+g, A3Σ+u, 5Σ+g, and 7Σ+u curves. Transport collision integrals for the 1Σ+g and 3Σ+u states have been calculated by representing the potentials for these states with the Hulburt-Hirschfelder potential. The5Σ+g state has a large local maximum which requires changes in the computational procedure used previously; a modified Hulburt-Hirschfelder potential has been used to represent the potential for this state. Collision integrals for the 7Σ+u state have been obtained by direct use of a recent theoretical potential for this state. The collision integrals are compared with results obtained in previous studies.
