X-ray Spectroscopy and Fluorescence Analysis

A number of mass comparisons have been made using a large Dempster-type mass spectrograph with a spark source. Packing fraction differences have been obtained for the doublets ${\mathrm{Si}}^{28}$-${\mathrm{Fe}}^{56}$, ${\mathrm{Si}}^{29}$-${\mathrm{Ni}}^{58}$, ${\mathrm{Si}}^{30}$-${\mathrm{Ni}}^{60}$, ${\mathrm{W}}^{183}$-${\mathrm{Ni}}^{61}$, ${\mathrm{W}}^{186}$-${\mathrm{Ni}}^{62}$, ${\mathrm{Pt}}^{192}$-${\mathrm{Zn}}^{64}$, ${\mathrm{Pt}}^{195}$-${\mathrm{Cu}}^{65}$, ${\mathrm{Pt}}^{198}$-${\mathrm{Zn}}^{66}$.
