The cross sections for production of neutron-rich silicon nuclei from Ref. [10] and the present work. The data with $A<43$ (i.e., $N<28$) are compared to the EPAX systematics for limiting fragmentation [17].Reuse & Permissions

Figure 4

The variation of the cross sections for the production of neutron rich nuclei as a function of the two-body $Q$ values [$Q_{\mathrm{gg}}$, left panels (a), (b)] and as a function of the one-body $Q$ value [$Q_{\mathrm{g}}$, right panels (c), (d)], see text for details. Upper panels (a), (c) show data for W (Ta), lower panels (b), (d) for Be targets. Each symbol is labeled with the respective mass number. Data from the present work (below the dashed lines in each panel) were combined with data from Ref. [10]. Solid symbols represent $Q$-value calculations based on the measured mass values, and open symbols based on the recommended values [21, 22]. The lines represent exponential fits of the most neutron-rich isotopes for each chain.Reuse & Permissions
