“…For two-electron systems, the beta decay of neutral 6 He atoms was also investigated experimentally as well as theoretically. The pioneering experimental results from Carlson et al [14] were first compared to the calculations of Wauters and Vaeck [15], and more recently to those of Schulhof and Drake [16]. Both calculations take into account electronic correlations and Auger emission and were found in good agreement with the experimental data for the single ionization probability.…”

Electron Shake-up and Shake-off Following6He Beta Decay

“…[9] for the corresponding one-electron 6 He + case. However, the comparison with experiment in Table 1 shows that the calculated recoil contributions are nearly an order of magnitude smaller than the measured values from the experiment of Carlson et al [5]. The disagreement between theory and experiment corresponds to the markedly di erent slopes in Fig.…”

“…As will be seen, the two terms are of opposite sign, and so there is extensive cancellation. After summing over all states and ionization stages, the unitarity condition (6) requires n (B 1S−nS + B 1S−nP ) = 0 [5]. Also, one can see by closure…”

“…The probability of ionization can be measured experimentally [41]. The probability of transition and ionization from the K-shell is defined as:…”
