Multipole Lines in the Spectra of Bi ii and Pb ii

Journal of the Optical Society of America, 1964
Spectra of Bi ii and Pb ii were excited by high-frequency oscillations in a quartz discharge tube conaining the vapor of the metal in an atmosphere of helium. The following five lines, corresponding to transitions among the five lowest levels of Bi ii belonging to the 6s2 6p2 electron configuration and forbidden by the Laporte selection rule, were ...

It was studied the influences of addition of protonodonor (MnO(OH)???) and protonoacceptor (Al???O?????nH???O) components on adsorption and mobility of ions Cu (II), Cd (II), Pb (II) into composite (hydr)oxides of Zr (IV), Sn (IV) and Ti (IV). It was found that increasing in ionic potential of forming metal of oxides bring to selectivity???s rising. It
