need help for finding a family font

Question

Although I have searched to find the family font used in the following formula I was not able to find it. I'm gonna typeset the red letters as they are in the formula, however, I don't know how to do it. Meanwhile, I used the tips suggested in here but it did not work out for me. It would be kind of you if you help me.

There remains the option of including the character as an image, but it looks like that your image is a somewhat-low-quality raster image and not e.g. vector graphics taken from a PDF. Still, you can retrace the boundary with some font creation program. ■ Even Detexify doesn't help here. — user202729, Dec 20 '21 at 04:49
Where are you taken your image, please? Have you the pdf file? — Sebastiano, Dec 20 '21 at 09:11
Dear @Sebastiano I don't have its pdf file. it was taken from a book named "The nuclear many-body problem" — AYBRXQD, Dec 20 '21 at 10:56
You might want to check the specimens in the mathalpha and unicode-math manuals for a decent match. Alternatively, you can use any OpenType or TrueType script font with \setmathfont[range=scr] in unicode-math. — Davislor, Dec 20 '21 at 11:48
Hi . I have seen the book. It Is old and It Is of springer. What Is the Page please? — Sebastiano, Dec 20 '21 at 19:49
@Davislor Hi very kind: here there is the book. http://hadron.physics.fsu.edu/~akbar/NuclearTextBook.pdf. I think that is the old euler script mathscr in math mode. It is since 1980 and I think that is a pure TeX. — Sebastiano, Dec 21 '21 at 07:51

It is probable that your text is from the pre-computer typesetting time. The closest font seems to be as follows:

\documentclass{article}
\usepackage[mathcal]{euscript}
\begin{document}
[
\mathcal{HR}
]
\end{document}

The notation does not appear to be standard. The screenshot below is taken from a recent Springer volume:

Younes W., Gogny D.M., Berger JF. (2019) Hartree-Fock-Bogoliubov Theory. In: A Microscopic Theory of Fission Dynamics Based on the Generator Coordinate Method. Lecture Notes in Physics, vol 950. Springer, Cham. https://doi.org/10.1007/978-3-030-04424-4_1

and uses only standard fonts.
