Source code

This is the source code used to generate the image (should also be available in the actual svg file not available in the svg file since I saved it as plain SVG):

\begin{eqnarray*}
    & \mathrm{n}^0 \longrightarrow \mathrm{p}^+ + \mathrm{e}^- + \bar{\nu}_e &\;\;\;\;\; \mathrm{p}^+ + \mathrm{n}^0 \longrightarrow ^2_1\mathrm{D}+\gamma \\
    &^2_1\mathrm{D}+\mathrm{p}^+ \longrightarrow ^3_2\mathrm{He}+\gamma &\;\;\;\;\; ^2_1\mathrm{D}+^2_1\mathrm{D} \longrightarrow  ^3_2\mathrm{He} +\gamma \\
    &^2_1\mathrm{D}+^2_1\mathrm{D} \longrightarrow ^3_1\mathrm{T}+\mathrm{p}^+ &\;\;\;\;\; ^3_1\mathrm{T}+^2_1\mathrm{De} \longrightarrow ^4_2\mathrm{He} + \mathrm{n}^0\\
    &^3_2\mathrm{He}+^4_2\mathrm{He} \longrightarrow ^7_3\mathrm{Li}+\gamma &\;\;\;\;\; ^3_2\mathrm{He}+ \mathrm{n}^0 \longrightarrow ^3_1\mathrm{T}+\mathrm{p}^+\\
    &^3_2\mathrm{He}+^2_1\mathrm{D} \longrightarrow ^4_2\mathrm{He} +\mathrm{p}^+ &\;\;\;\;\; ^3_2\mathrm{He}+^4_2\mathrm{He} \longrightarrow ^7_4\mathrm{Be} +\gamma\\
    &^7_3\mathrm{Li}+\mathrm{p}^+ \longrightarrow ^4_2\mathrm{He} + ^4_2\mathrm{He} &\;\;\;\;\; ^7_4\mathrm{Be} +\mathrm{n}^0 \longrightarrow ^7_3\mathrm{Li} + \mathrm{p}^+
\end{eqnarray*}

Using align rather then eqnarray should work better but I have yet to figure out how to activate ams packages in TexText. /Lokal_Profil 14:31, 16 June 2008 (UTC)

Protons don't add correctly

The fourth entry in the first column doesn't add correctly: He-4 + He-3 cannot give Li-7 + photon because the protons don't add correctly.
