Examples in which Vegard's law is strictly obeyed are very scarce (see e.g. Pearson (1972)). A better estimation of the trends in the volume of formation of the sp-bonded metals may be obtained using first-order pseudopotential perturbation theory (Girifalco, 1976). Namely, the formation ...
We have, in our laboratory, two large mass spectrometers which may be operated routinely with a resolving power of 100,000 or more. The older and larger instrument 1 ("Manitoba I") has a 2.7 m radius and is of a modified Dempster geometry. While it was not used for the work reported...
