Re:

Seems like my recommendations from more than 20 years ago (without the use of numerical techniques I might add) have stood up well.

Per Freehafer [1], circa 1930’s , is a lot earlier than that.

@WHG

Thank you!

That paper was referenced in my very first paper on the subject. It is useful, but no attempt is made to apply it to a real situation.

Thats it. You can also look at Methods of Theoretical Physics also by Morse, but it's a two volume set that can get expensive. Buying used on Amazon is usually a great deal. I buy lots of these earlier era classics that way.

EG,

The Feshbach Family is still publishing it at a resonable price.

Wow - thanks for that. I have seen them even cheaper on Amazon as a used set. I bought "Vibration and Sound" used on Amazon. Turns out it was a first addition in pristine condition - for $25.
