The field being relatively new also heavily influenced the scientists being so young.
The age of modern quantum mechanics started in 1925. Heisenberg received the Nobel Prize for his 1927 work on the uncertainty principle in 1932 at the age of 31. 10 years later the Manhattan Project started.
There just weren’t that many older scientists with training in the field. Young PhDs were only a few years removed from the first discoveries that enabled nuclear physics to leap forward.
