Precise half-life measurement of the superallowedβ+emitterSi26

Precise Half-Life Measurement of Ga

In last year’s Progress Report we reported on measurements of the β-decay of Ga, including a preliminary value for its halflife [1]. We report here on an additional measurement of the half-life focused on exposing systematic effects that could affect the result. We obtained Ga from the MARS recoil spectrometer by bombarding a cooled hydrogen gas target with Zn at 42A MeV. Special care was taken...

Precise Half - Life Measurement of 22 Mg

As part of our program [1] to test CKM unitarity via superallowed ∃-decays, we reported in last year’s Progress Report [2] that we were well advanced in making a measurement of the half-life of Mg. At that time we had obtained a preliminary result but had not yet fully explored all possible systematic errors. Subsequently, an additional experiment was performed at the MARS spectrometer with our...

“the effect of risk aversion on the demand for life insurance: the case of iranian life insurance market”

abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...

Precise Half Life Measurements: the Case of C

V.E. Iacob, V. Golovko, J. Goodwin, J.C. Hardy, N. Nica, H.I. Park, L. Trache, and R.E. Tribble The half-life of C was measured as part of our program to test the unitarity of the CabibboKobayashi-Maskawa (CKM) matrix via 0 –> 0 superallowed β transitions; the case of C is of particular interest because of its higher sensitivity to the presence of scalar currents [1]. The C half-life has been m...
