The effectiveness and accuracy of the proposed analytical expressions for SFMTR matrix elements are shown by calculation of concrete cases.eninfo:eu-repo/semantics/closedAccessMultipole radiationMultipole transition Matrix elementsDiffuse and planetary nebulaeExponential type orbitalsSelf-frictional quantum numbersArticle357110.1007/s10509-015-2241-7Q3WOS:0003543924000302-s2.0-84928337069Q2
