|Electron-impact cross section data has been added for many molecules and atoms. Version 3.0 also includes a new graphical design and user interface, with the data for atoms and molecules accessed through different interfaces. Additions to the database include excitation cross sections for atoms H, He, & Li; and ionization cross sections for atoms B, C, N, O, Al, Ga, In; and for molecules C2H3, C3H3, C3H4 (allene & propyne), C3H5, C3H6, C4H2, C4H4, C4H6, C4H8 (1-butene, trans-2-butene & isobutene), C6H2, C6H6 (fulvene), SiF4, HO2, and six Freon molecules (CClF3, CCl2F2, CCl3F, CHClF2, CHCl2F, CH2ClF). The molecular orbital notation was modified for many of the molecules.|
|New theoretical data along with relevant references were added for the following hydrocarbon ions: H3O+, CH2+, CH3+, CH4+, C2H2+, C2H4+, and C2H6+.|
|New theoretical and experimental data along with relevant references were added for H2+, N2+, CO+, CH+, H2, He, NO2, BF, BF2, BF3, BCl, BCl2, BCl3, CF, CF2, CF3, CHO, CH2O, and C2H3O. Molecular orbital data (B, U, N, Q) for deep inner shells (mostly K shells) of molecules with heavy atoms have been added to all molecules.|
|One experimental data set was added for H2O.|
|Single Differential Cross Section data for H, He, and H2 were included. Data for halogen compounds were updated, and the graphing capabilities were expanded.|
|Data for halogen compounds were added, and additional internal changes were made.|
|Data for CH and C2H2 were added. Also added were BEB cross sections in tabular form for all atoms and molecules.|
