Decay Heat Measurement of Actinides at YAYOI

Measurement of theW boson polarization in top decay at CDF at sqrt(s)=1.8 TeV

Measurement of the Decay T + Pv T

_ The decay r + pv is studied in r pair production by e+eannihilation at @ = 3.77 GeV, 0.20 GeV above rr threshold. The branching fraction is measured to be B(r + pv) = (23.0 f 1.3 f 1.7)%. The measured distribution of the helicity angle of the charged pion from the p decay agrees with the theoretical prediction. -. Submitted to Physical Review Letters ^ .:_* -

Measurement of the Pseudoscalar Decay Constant

Measurement of prominent eta-decay branching fractions.

The decay psi(2S) --> etaJ/psi is used to measure, for the first time, all prominent eta-meson branching fractions with the same experiment in the same dataset, thereby providing a consistent treatment of systematics across branching fractions. We present results for eta decays to gamma gamma, pi(+)pi(-)pi(0), 3pi(0), pi(+)pi(-)gamma and e(+)e(-)gamma, accounting for 99.9% of all eta decays. Th...

Coordination Chemistry of the Actinides

recognize +4 and +6 as the main oxidation states for uranium and +4 as the only important oxidation state for thorium; appreciate that coordination numbers of >6 are the norm; be familiar with the main features of the chemistry of the other actinides, and appreciate the transition in chemical behaviour across the series; appreciate the importance of nitrate complexes; recognize the characterist...
