Radio recombination lines from planetary nebulae
Abstract
The paper presents seven radio recombination lines observed from NGC 7027, in the principal quantum number range H66-alpha to H110-alpha. A summary of the observations of radio recombination lines from eight other planetary nebulae is also presented. Consideration is given to line broadening for these nebulae.
