The low resolution of your sample does not give us much to work with, unfortunately.

My best guess is that the body copy is set in Times. It seems slightly more condensed that most modern digital versions, but that could also be a function of the phototypesetting process (optically stretching or slanting type was one of the possibilities with phototypesetting technology).

The chapter title seems to be Bodoni Poster Italic. It is at slightly more of an oblique slant than modern digitals, but still recognizable, and again probably given the additional slant with a phototypesetter.

The word /in/ between /Atoms/ and /Motion/ is in a different type, looks like an oblique sans, but there is neither sufficient clarity nor diversity of letters here to guess at what that might be.

Andrew correctly identified the fonts, but the book was almost certainly set in hot metal. Most US textbooks were set on the Linotype in 1964, when Addison-Wesley published the first edition of the Feynman Lectures. Monotype, another automated hot-metal process, was more widely used in the UK, and was often used in the US for books with tabular matter and complex equations. Photocomposition was not in widespread use for books until the 1970s.
The title Physics in Motion was probably set by hand in foundry type, which might explain why the two different fonts don't have a common baseline.
