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 &= x \,{\mathrm e}^{-\frac {x^{2}}{2}} \operatorname {KummerM}\left (\frac {7}{8}, \frac {3}{2}, 2 x^{2}\right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {{\mathrm e}^{\frac {x^{2}}{2}} y}{x \operatorname {KummerM}\left (\frac {7}{8}, \frac {3}{2}, 2 x^{2}\right )}\right ] \\ \end{align*}

\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= x \,{\mathrm e}^{-\frac {x^{2}}{2}} \operatorname {KummerU}\left (\frac {7}{8}, \frac {3}{2}, 2 x^{2}\right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {{\mathrm e}^{\frac {x^{2}}{2}} y}{x \operatorname {KummerU}\left (\frac {7}{8}, \frac {3}{2}, 2 x^{2}\right )}\right ] \\ \end{align*}
