Charge-symmetry breaking (CSB), after electromagnetic effects have been removed:

• \( a_{pp}= -17.3 \pm 0.4 \hspace{0.cm} \mathrm{fm} \)
• \( a_{nn}=-18.8 \pm 0.5 \hspace{0.cm} \mathrm{fm} \). Note however discrepancy from \( nd \) breakup reactions resulting in \( a_{nn}=-18.72 \pm 0.13 \pm 0.65 \hspace{0.cm} \mathrm{fm} \) and \( \pi^- + d \rightarrow \gamma + 2n \) reactions giving \( a_{nn}=-18.93 \pm 0.27 \pm 0.3 \hspace{0.cm} \mathrm{fm} \).

Charge-independence breaking (CIB)

• \( a_{pn}= -23.74 \pm 0.02 \hspace{0.cm} \mathrm{fm} \)
