Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= {\mathrm e}^{-\frac {3 x^{2}}{2}} \operatorname {KummerM}\left (-\frac {1}{6}, \frac {3}{2}, \frac {3 x^{2}}{2}\right ) x\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {{\mathrm e}^{\frac {3 x^{2}}{2}} y}{\operatorname {KummerM}\left (-\frac {1}{6}, \frac {3}{2}, \frac {3 x^{2}}{2}\right ) x}\right ] \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= {\mathrm e}^{-\frac {3 x^{2}}{2}} \operatorname {KummerU}\left (-\frac {1}{6}, \frac {3}{2}, \frac {3 x^{2}}{2}\right ) x\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {{\mathrm e}^{\frac {3 x^{2}}{2}} y}{\operatorname {KummerU}\left (-\frac {1}{6}, \frac {3}{2}, \frac {3 x^{2}}{2}\right ) x}\right ] \\ \end{align*}
