energy requirements for fusion

[Deepak247]

How much kinetic energy is required for a proton and neutron to fuse(in any given condition)?

I've also heard that a proton-proton fusion is impossible because it needs a lot of kinetic energy, but how much(also comparable to p-n fusion)?

I don't know too much on proton-neutron fusion, but I assume that it would require very little energy, if any, as the neutron is electrically nuetral and wouldn't be pushed away from the proton.

Proton-Proton fusion is most definately possible, but the high energy requirements mean it isnt an option for Fusion power. It does take place in stars however.

Zero.

Deepak, you're going to have to take some responsibility for your education. You refuse to learn the basics, and then expect us to do all the work. This is deeply disrespectful of the other people in this forum. Like I said before, the progression is elementary physics, quantum mechanics, nuclear physics and then and only then, will nuclear physics as applied to fusion make any sense. If you are too lazy to put in the work to understand the beginning of this progression, you won't understand the answers you get. You're wasting your time and ours.

Mr vanadium sir,

You're probably right, I am lazy, but yet determined to gain knowledge,

I may be asking questions way too far from my grasp of current studies on physics (which is still ongoing), but this is my interest and no matter how much i try i just can't let go of it,

Its my habit to try to learn in advance, If this is what's causing problems to you then

"I APOLOGIZE"

I will never ask any other question on this forum ever again......ever,

Bye.

No need to leave forever man. Spending a little time on Wikipedia or other sites can greatly expand your basic knowledge. Then, if you don't understand something, feel free to ask.

Thanks Dr. Akkith, I'll heed on your advice

The kinetic energy required is completely dependent on the external conditions set. I would also like to point out that a proton with a neutron is very loosely defined as fusion considering that existing in isolation the two would eventually pull together into one nuclei. Also proton-proton fusion is seen in exotic particles however would only remain stable in normal conditions if the strong force were slightly, two percent, stronger.

Also in reply to Vanadium, I answer many of his questions because I am experienced in the field, but I see you on here many times but I rarely see you actually answering questions. People come here to learn, and you should respect all levels of intelligence, whether they are professional like myself or a beginner like Deepak. If one comes to learn then teach them. It is only ever a waste of your time if you choose to take the time. In fact I would say your posts are a waste of time because they serve neither to teach nor to point toward a teacher with enough knowledge to assist. If basic background is needed then explain or let someone else explain it. As a final point I would like to say quantum physics is unnecessary in your supposed line up of needed education to understand this. It is merely an advanced topic, but not needed for understanding.

I hope I could be of assistance.

Isn't proton-proton fusion seen normally in stars? I've read that two protons fuse by having one turn into a neutron and releasing a positron and a neutrino.
