# Setting the bibliography RevteX along the text while keeping the number in sections

I have this code for my Latex, using revtex 4 :

\documentclass[twocolumn]{revtex4}
\usepackage[T1]{fontenc}
\usepackage{blindtext}

\begin{document}
\section{Introduction}
\blindtext \cite{REF}

\begin{thebibliography}{99}
\bibitem[Citation]{REF}
Somebody.
\newblock Some title
\newblock \textup{Some Journal}. \textbf{0}\penalty0 (0):\penalty0 0--1 (2021).
\end{thebibliography}

\end{document}


The result is :

But I would like the bibliography not to start in a new set of column, but rather on the same column as the text.

Following this answer if I change to : \documentclass[prl,twocolumn]{revtex4}, this is fixed, but a new problem appears that I lose the numbers in the section.

Here's a possibility, copying the corresponding piece of code from aps4-2.rtx. There might be better ways but I've never really got the hang of RevTeX's management of different journal styles.

Note that revtex is 20 years old and shouldn't be used for anything new; the current version is revtex4-2.

\usepackage[T1]{fontenc}
\usepackage{blindtext}
