Daily dietary intake of minor and trace elements by upper social groups in Taiwan

Sixteen minor and trace element contents of diet samples from three different social population groups in Taiwan were determined. Samples were prepared using duplicate portion technique by collecting the 15 subjects ate and drank during a 3-day period. Samples were homogenized, freeze-dried, and elemental concentration of minor and trace elements were determined by instrumental neutron activation analysis. Elemental concentrations and daily dietary intake of the elements were compared with those in the other nations, and possible origins were discussed.

Decay of 83-min 139Ba to levels of 139La and the decay of 18-min 141Ba to levels of 141La.

The level structures of odd proton La139 and La141 have been studied in γ-ray singles, Compton-suppressed singles, coincidence, and angular correlation experiments. No evidence was observed to support the existence of any levels in La139 in the gap between the 166-keV d5/2 level and the 1209-keV (1/2)+ level, even though data were accumulated long enough to observe indirect feeding of the (1/2)+ level. Additional spin and parity assignments are suggested for a number of levels in La141 based on angular correlation measurements.

Decay of 83-min /sup 139/Ba to levels of /sup 139/La and the decay of 18-min /sup 141/Ba to levels of /sup 141/La
