The txfonts
package used to be the answer, but since some days a new package has been developed based on the first one, with new metric files for fonts that should avoid some of the weaknesses shown by txfonts
:
\usepackage{newtxtext,newtxmath}
A word of advice about the TeX distribution: disk space is not a big issue nowadays. Unless you're running TeX on a very small device, do a full install.
pslatex
is really an obsolete package. You can use mathptmx
, as already suggested, or
\usepackage{newtxtext,newtxmath}
(which requires an updated TeX distribution).
mathptmx
newtxtext
+ newtxmath
Here is the source. Notice how the result is obtained more simply than you did (everybody must learn, when using a new tool).
\documentclass[a4paper]{article}
\usepackage{amsmath} % For maths symbols.
%%% uncomment one of the following and comment the other
\usepackage{newtxtext,newtxmath}
%\usepackage{mathptmx}
\begin{document}
Times New Roman.
$\beta=3\alpha$
$\beta=3\alpha$
$\alpha, \beta, \gamma, \delta, \epsilon, \lambda, \phi, \rho, \varphi, \omega$
\begin{equation}
t_{1/2} = \frac{\ln(2)}{\lambda}.
\end{equation}
\end{document}
(The difference in size is an artifact of the image production.)
