The 30.8 keV {(1/2)}^{\ensuremath{-}}isomeric state in _{41}^{93}\mathrm{Nb}decays by an M4transition to the {(9/2)}^{+}ground state. We have measured the Kshell internal conversion coefficient {\ensuremath{\alpha}}_{K}for this transition in order to test the validity of current methods of calculation for a case with relatively low atomic number, low transition energy, and a high value of {\ensuremath{\alpha}}_{K} Taking the fluorescence yield of niobium to be 0.751(4), we o...

We have measured the branching ratio for the superallowed {0}^{+}\ensuremath{\rightarrow}{0}^{+}\phantom{\rule{4pt}{0ex}}\ensuremath{\beta}transition from ^{34}\mathrm{Ar}to be 0.9448(8), and determined its ftvalue to be 3058.1(28) s, a result with \ifmmode\pm\else\textpm\fi{}0.09 precision, which is a factor of 3 improvement over the previous result based on current world data. The ftvalue ratio for the mirror pair of superallowed transitions ^{34}\mathrm{Ar}$\ensuremath{\r...

Superallowed \ensuremath{\beta}decay is an important tool in characterizing the vector component of the weak interaction. Precise \ensuremath{\beta}decay results presently give the best measurement of the up-down quark weak-mixing element, {V}_{u\phantom{\rule{0}{0ex}}d} This new result completes the measurement of a second set of superallowed mirror transitions ({}^{26}i-{}^{26m}l and {}^{26m}l-{}^{26}g in this case) and has the precision to constrain the theoretical isospi...

We have measured the half-life of 30S, the parent of a superallowed 0+-to-0+ beta transition, to high precision using very pure sources and a 4pi proportional gas counter to detect the decay positrons. Our result for the half-life is 1.17992(34) s. As a byproduct of this measurement, we determined the half-life of its daughter, 30P, to be 2.501(2) min.

Abstract We present a method of analysis of nuclear decay spectra affected by extending dead-time, in which a non-trivial, but relatively simple correction for dead-time losses is applied to produce an estimate of the spectrum in the absence of dead-time, with negligible bias and negligible deviation from the original Poissonian statistics. The method requires the measurement of arrival times of all observed decay events, but it does not require any knowledge about the dead-time or the nuclear d...
