High-resolution study of theBe9(He3,Scholl1, Fujita2, Adachi3 et al. 2011Phys. Rev. C492220View full textAdd to dashboardCite

“…5). As mentioned, the β + decay of 9 C to 9 B [34,35,38] and the β − decay of 9 Li to 9 Be [37] have been measured with high precision. These measurements show that the transitions from the ground states of these nuclei to the ground states of 9 Be and 9 B have very weak B(GT) strengths, while transitions to the highly excited states have very large B(GT) strengths.…”

“…4). Studies of the 9 C β + decay were carried out by Buchmann et al [34], Bergmann et al [35] and Mikolas et al [36], and studies of the 9 Li β − decay by Nyman et al [37] and Prezado et al [38].…”

Beta-neutrino recoil broadening in?-delayed proton emission of32Ar and33Ar

“…Here we follow the formulation of Nyman et al [6] and give the main formulas in the following. The kinematic shift, t, of a proton with kinetic energy Ep and mass mp is t= -k(pp cos 0pp+P~ cos Opt),…”

Measurement of electron antineutrino oscillation based on 1230 days of operation of the Daya Bay experiment

“…After decay, the nucleus fragments into an energetic neutron and two α particles. An empirical model was constructed to match the observed branching β-n decay fractions [45], and observed neutron and α energy spectra [46,47]. Although their impact on the spectrum was minor, the contribution of the neutron and α's to the observed energy were included based on the detector response model previously discussed.…”
