Normalization factor $R$ with statistical uncertainties for the measurements at $E_{\text{c.m.}}=300\mathrm{keV}$ in charge state $4^{+}$. The solid line represents the average, the dotted lines its statistical uncertainty, and the dashed lines its total uncertainty.Reuse & Permissions

Figure 5

Time of flight through the separator for $E_{\text{c.m.}}=258\mathrm{keV}$ and recoil charge state $4^{+}$. The solid blue line represents all coincidence events; the events that passed software cuts on both MCP and separator time-of-flight are shown in red (dashed line).Reuse & Permissions

Figure 6

Time of flight between the MCPs for $E_{\text{c.m.}}=258\mathrm{keV}$ and recoil charge state $4^{+}$. Higher channels correspond to a shorter time of flight, and thus higher velocity. The solid blue line represents all single events; the green dashed line represents all coincidence events; the coincidence events that passed software cuts on both MCP and separator time of flight are represented by the red dotted line. The additional peaks are due to the “leaky” ${}^{17}$O beam. The leaky beam can have a range of different energies, since it must scatter at least once in the separator in order to be transmitted to the MCPs. The abscissa represents the output amplitude of the TAC.Reuse & Permissions

BGO $\gamma$ spectrum taken at $E_{\text{c.m.}}=470\mathrm{keV}$. The solid blue line is the data, the dashed red line is the fit including transitions to excited states at 937, 2523, 3062, 3791, 3839, 4116, 4398, and 4964 keV.Reuse & Permissions

$S$ factor $\times$ charge state fraction for charge states $3^{+}$, $4^{+}$, $5^{+}$, and $6^{+}$ at $E_{\text{c.m.}}=300\mathrm{keV}$; measured values are in blue, the Gaussian fit is in red, and the calculations from Ref. [17] normalized to the measured values are shown in green.Reuse & Permissions
