How atomic bombs work and why Manhattan Project scientists designed two types of bombs during WWII

Business Insider 09 Aug 2023
The center of atoms is comprised of tiny particles called protons and neutrons. Fission, which was discovered in 1938, occurs when an atomic nucleus is hit with a neutron. It splits, producing two lighter elements and, more importantly, a few neutrons and some energy — both are key to atomic weapons.

How Accurate is Christopher Nolan's 'Oppenheimer'?

Quillette 01 Aug 2023
Instead of high-energy neutrons hitting nuclei like cannonballs, a better way to picture it is that neutrons move around and get pulled into nuclei by nuclear forces ... Now, when a neutron collides with the nucleus of a reactor material, there's a chance it can either bounce away, wasting some energy, or get absorbed by the material.

The science you should understand before seeing 'Oppenheimer'

Business Insider 22 Jul 2023
Fission occurs when a neutron slams into an atom, splitting its nucleus in half ... Each element has a set number of neutrons, protons, and electrons that define it. A radioactive isotope, aka radioisotope, has a different number of neutrons but the same number of protons, making its nucleus unstable and thus more reactive.

An even closer look at the 'doubly magic' tin-100 nucleus

Phys Dot Org 20 Jul 2023
This is the case of the tin-100 nucleus, which has 50 protons and 50 neutrons. But this special doubly magic nucleus—it is also the heaviest such nucleus comprising protons and neutrons in equal number—is particularly challenging to produce in the lab and is relatively short-lived.
