Kβ satellite spectrum of metallic nickel

Abstract

The electron excited Kβ emission spectrum of metallic nickel has been recorded photographically by a 40 cm curved muscovite mica spectrograph of the Cauchois type, and analysed by a microphoometer. Both high and low energy sides of the Kβ 1.3 line have been studied in detail. On the high energy side, a new satellite at 1492.7 xu (8288.5 eV) has been observed and has been named as β 7. The presence of the satellites ξ III, ξ IV and β IV 1 reported earlier, each in only one study, has been confirmed. The last line has been renamed as β 6. Many of the other satellites, reported earlier, have been remeasured. The transition assignments to these satellites, based on HFS calculations of 1s(−1) nl(− m)− nl(− m)3p(−1); n = 2, 3; m = 1, 2; transition energies, have been presented. On the low energy side of the Kβ 1.3 line, many new features have been observed. The presence of the satellites β η and β q, reported earlier, has been confirmed. It has been reported that many of these low energy satellites can be assigned to various 1 s(−1)−3l,(−1)3l,( t ̄ 1) , ( l i = 0, 1; l i = 0, 1 and 2) radiative Auger transition.
