An approximate solution for electron trajectories in a cylindrical field is presented and discussed in connection with the 127° spectrometer originally proposed by Hughes and Rojansky. The approximate solution is compared to a numerical one, and is used to calculate the line shape in a few special cases.
A method which determines phase shifts from experimentally measured collision cross-section data by means of a linear regression analysis is discussed. This method also provides a means to normalize the measured data. An application to low energy electron-helium scattering data is included.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
