| Jan 28, 2020 at 16:51 | comment | added | Emilio Pisanty | @Korra Inverse alpha decay, often called alpha capture, has indeed been observed experimentally (though I'm unsure whether it's been observed for the particular nuclei you mention). | |
| Jan 28, 2020 at 15:32 | comment | added | Korra | Okay. Can this be attempted experimentally? I mean bombarding Po-212 alpha particle in the right manner. | |
| Jan 28, 2020 at 15:22 | comment | added | John Dvorak | @Korra the process of an alpha particle embedding itself into a nucleus is the same as a spontaneous emission of an alpha particle by the new nucleus happening backwards. Time reversal invariance means the same things happen in reverse if you reverse time. In rigid body physics, time reversal means stopping everything at the same time and sending it in the opposite direction and with the same speed, for example. | |
| Jan 28, 2020 at 14:57 | comment | added | Korra | Thanks @John Dvorak for the support ready explanation though I looked it up on PSE. But what does time reversal has to do in this? | |
| Jan 28, 2020 at 14:52 | comment | added | John Dvorak | @Korra unitary evolution = time passes while you aren't looking at stuff. | |
| Jan 28, 2020 at 14:46 | comment | added | Korra | What is unitary evolution...? And why do we have to consider time reversal? Also, what do you mean by"sufficient length of time"? The velocity of the incoming alpha particle?? | |
