The 1.00 m radius high resolution mass spectrometer at the University of Manitoba ('Manitoba II') has been used to determine the atomic masses of 47Ti and 48Ti. These data are somewhat superior in precision to existing values and improve the reliability of atomic mass data in that region of the mass table.

The 1.00 m radius high resolution mass spectrometer at the University of Manitoba ("Manitoba II") has been used to determine both atomic masses and atomic mass differences for all the naturally occurring isotopes of Hg with a precision superior to existing values. The mass difference data are in excellent agreement with recently tabulated values, while the atomic masses themselves differ significantly.

Resolution Mass

The 1.00-m radius, high resolution mass spectrometer at the University of Manitoba has been used to determine the spacings of a series of mass spectral doublets. These give improved values for the mass differences between the stable nuclides in Tl, Pb, and Bi and relate these values to previous atomic masses and mass differences for the isotopes of Hg. A least-squares adjustment has been performed on all available atomic mass data (including the mass spectroscopic results from this laboratory) for the region 78 ≤ Z ≤ 84.

The Rare Earth

A high-resolution mass spectrometer has been used to determine precise atomic-mass differences for 31 mass spectral doublets amongst the rare-earth chlorides. The precision of these determinations is in the range 0.6 μu to 3.8 μu, i.e. (2.5 to 25) × 10−9. The new data, when combined with previous data from this laboratory and with the known 37Cl–35Cl difference, provide mass-spectroscopically-derived connections between all naturally occurring odd-A nuclides from 141Pr to 169Tm and between all even-A nuclides from 142Nd to 170Er.

Resolution Mass

A high resolution mass spectrometer has been used to determine new values for 16 atomic mass differences involving naturally occurring isotopes for [Formula: see text]. These new determinations, which were derived by means of a computer assisted peak matching system, have a precision ranging from 0.6 to 2.0 μu (0.6 to 1.8 keV) and thus are generally more precise than the corresponding nuclear reaction or decay Q values available in the region.
