我正在尝试写一个包含一些单词的化学方程式。该方程式如下所示：
我为此编写的代码是
\begin{equation*}
^4_2He + ^9_4Be \longrightarrow ^{12}_6C + Highly \quad Penetrating \quad radiation
\end{equation*}
它产生的输出是这样的：
但我希望“高穿透辐射”部分像第一张图片一样以垂直顺序书写。我该如何实现？
答案1
我会更新竖版
用于\text{..}方程式中的普通（解释性）文本。
然而，在我看来，最好使用\ce{...}from 来显示同位素和箭头。我给出了一些变体：mhchem
\documentclass{article}
\usepackage[version=4]{mhchem}
\usepackage{mathtools}
\begin{document}
Original version
\begin{equation*}
^4_2He + ^9_4Be \longrightarrow ^{12}_6C + \text{Highly penetrating radiation}
\end{equation*}
Some usage of \verb!\ce!
\begin{equation*}
\ce{^4_2He} + \ce{^9_4Be} \longrightarrow \ce{^{12}_6C} + \text{Highly penetrating radiation}
\end{equation*}
Replacing the \verb!\longrightarrow!
\begin{equation*}
\ce{^4_2He + ^9_4Be -> ^{12}_6C} + \text{Highly penetrating radiation}
\end{equation*}
No equation environment at all ('inline')
\ce{^4_2He + ^9_4Be -> ^{12}_6C + Highly penetrating radiation}
\end{document}
垂直版本，\Centerstack来自stackengine
