A Class of Methods for Solving Nonlinear Simultaneous Equations
TL;DR: In this article, the authors discuss certain modifications to Newton's method designed to reduce the number of function evaluations required during the iterative solution process of an iterative problem solving problem, such that the most efficient process will be that which requires the smallest number of functions evaluations.

Rate of collisional excitation in stellar atmospheres
TL;DR: In this article, an approximate formula is proposed to compute the cross-section for excitation by electron impact for the op, where the crosssection is defined as the number of electron impacts.
