Edit appearance of the text in axis label for an XY plot?

The following piece of code is intended to label the x-axis " ln <R(t)> " and the y-axis " ln p’(t) ". This plot will go in a paper that I’ll submit for publication, so it needs to look nice. My problem is that the y-axis label appears as " ln (t)p’ " rather than " ln p’(t) ". How do I fix that??? Thanks!

FrameLabel -> {"ln " AngleBracket[Style["R(t)", Italic]], 
  "ln " Superscript[Style["p", Italic], \[Prime]] Style["(t)", 
    Italic]}

Plot[10 Sin[t] + t^2, {t, -10, 10}, Frame → True,
FrameLabel → {"In " Style[“R(t)”, Italic],
"In " Style[“p’(t)”, Italic]}]

Plot[10 Sin[t] + t^2, {t, -10, 10}, Frame → True,
FrameLabel → {"ln " Style[“R(t)”, Italic],
"ln " Style[“p’(t)”, Italic]}]

Thank you for your reply! As I am preparing the plot for publication, I specify that the font is " Times ". When I use your suggested solution " Style[“p’(t)”,Italic] ", the result is good except that the prime is upright instead of slanted.

You are welcome! You can try this:

Plot[10 Sin[t] + t^2, {t, -10, 10}, Frame -> True, 
 FrameLabel -> {"ln " Style["R(t)", Italic], 
   "ln " Style["p'(t)", Italic]}, LabelStyle -> Directive[Italic]]
