Branching ratios in nucleon decay
Il Nuovo Cimento A, 1982Two-body branching ratios in nucleon, decay are evaluated for differentSO10 schemes and for two plausible choices of generation mixing, by starting from theSU5 estimate by Karl and Kane. While the Cabibbo-suppressed modes should be required to get information on the mixing scheme, the unsuppressed modes would suffice to distinguish between models of ...

125Sb to 125mTe branching ratio
Applied Radiation and Isotopes, 1998Abstract The ratio of the 125 Sb β -branch to the long-lived isomeric state 125m Te (57.4 days) has been measured by γ -spectrometry to be 0.231±0.010. Since the liquid scintillation counting efficiency is high for both 125 Sb (90%) and 125m Te (100%), the determination of this branching ratio by liquid scintillation spectrometry requires one ...

Abstract The decay modes of levels at 3.943, 4.350 and 4.830 MeV in 26Mg are established and those of levels at 1.805 and 2.941 MeV are confirmed using the 25Mg(d, pγ)26Mg reaction. The protons were detected at 0° and the gamma rays observed in coincidence with selected proton groups.

Relative branching ratios in UI
Optics Communications, 1977Abstract We describe some results obtained from a simple method for measuring the relative decay rates of an excited level of uranium to the various permitted lower states. Both one- and two-photon excitations have been used.

Abstract The 10 B(nα) branching ratio has been measured in the energy range 23 ev−0·5 MeV. The results show that the ratio is constant for neutron energies up to about 130 keV.

A measurement of the branching ratio, R=[mathematical description for a branching ratio]
1979The Branching Ratio R= [See Thesis for formula] has been measured on the basis of 100,000 π￫ev events. Pions were provided by the TRIUMF cyclotron. The muons produced by pion decay themselves subsequently decay via [Formula]. The mono-energetic positrons from pion decay and the "Michel" distribution of positrons from muon decay were ...

The branching ratio $��\to ��^+��^-$ revisited
2016We analyze the most recent data for the pion vector form factor in the timelike region, employing a model-independent approach based on dispersion theory. We confirm earlier observations about the inconsistency of different modern high-precision data sets.

Branching Ratios in Activated Systems
The Journal of Physical Chemistry A, 1997Branching between reaction channels in activated systems is often observed to vary with changes in the potential energy surface as Δln(k1/k2) ∝ Δ(Δ − Δ ). RRKM calculations demonstrate that in many, but not all, cases the log−linear relationship accurately describes branching in nonthermal distributions of reactants with energies well above the ...

Alpha branching ratio of 227Ac
Journal of Inorganic and Nuclear Chemistry, 1970Abstract The alpha branching ratio of 227 Ac has been determined by two independent methods. The intermediate means from the two methods were in good agreement: (1·3802±0·0069) per cent and (1·3799±0·0045) per cent. The weighted grand mean from 12 determinations was (1·3800±0·0036) per cent.
