I will be needing to pick up a nuclear physics book one of these days. Krane seems to be a pretty popular recommendation, but the price is a little but high. I've heard good things about Blatt, but never in comparison to Krane. So how does Blatt hold up to Krane? Are they suitable for the same...

Hello! I apologize in advance if this has been asked before, or if it more properly belongs in the career section - I wasn't sure since I'm still at university. I'm currently in the middle of my undergrad studies in physics with an astronomy focus. My plan has been to go on to grad school to...

Say a uranium-238 nucleus with angular momentum II decays to thorium-234 plus an alpha particle. Will the sum of the angular momenta of the thorium-234 nucleus and the alpha particle equal II? What if a photon was emitted during this process, would Ithorium+Iα+hbar=II? thanks

When a nuclear reactor is in a critical state, the neutrons released in each fission trigger an average of exactly one additional fission. If the average number of additional fissions triggered rises above one, the reactor enters a supercritical state in which the fission rate and the thermal...

I am about to graduate with a physics Ph.D. My University is very strong in optics, photonics and electromagnetism, and even basic quantum mechanics (for topics like entanglement and solid state physics) but rather weak in nuclear physics. Thing is, nuclear physics has always fascinated me and...

Hello all. I was just wondering what kind of things I would need to know if I wanted to become a nuclear physicist? I'll be honest, I've never been very strong in any math or science. Almost every teacher I've had in math or science has pretty much crushed what little confidence I had in both...

I have this test and there are few questions that I can't answer or don't know if I'm right. 1) You need to measure the half-life of some random element. What instruments do you need? What values you need to measure? What results you will probably get? 2) You need to check the radioactivity...

As the title suggests, does anyone know any good books for (introductory) Statistical Mechanics and/or Nuclear Physics? Any input is greatly appreciated :-p.

What is the difference between particle physics and nuclear physics? Two areas is often treated as a single region as "nuclear and particle physics". Some author of paper, however, distinguish sharply between the two regions. I want to know the boundaries of particle physics and nuclear physics.

Can you recommend a good book on the theoretical side of nuclear physics?
