Nuclear force Definition and 71 Threads

Hello: I've heard that Yukawa's interaction could explain the nuclear force, but I also heard that the strong nuclear force is explained by QCD, Could you please explain me more about it ? Thanks a Lot

I'm a physics undergraduate student who has recently finished a special relativity class, but haven't done a nuclear physics class yet, so if I'm mistaken anything about nuclear physics, please object. I was pondering about a situation while doing my special relativity class which I haven't...

Homework Statement This is from Advanced Physics by Adams and Allday. Spread 8.26, Q 2. a) The strong nuclear force cannot fall off as an inverse-square law. Why not? b) Give a reason for thinking that the strong nuclear force must become a repulsion at very short range. Homework...

Does electrons contribute to nuclear force.? As per name 'nuclear force', it shouldn't contribute. Even if it does it should be to a very little extent. right?

My (high school) physics teacher was telling us about quarks and how the colour force between quarks is responsible for the strong nuclear force among baryons. He also claimed that unlike other forces, this force became stronger over a distance which is why it requires a lot of energy to...

While reading the book " Cosmic Catastrophes. Supernovae, Gamma-Ray Bursts and Adventures in Hyperspace" by J.Craig Wheeler I came across this line: "By the happenstance of the nature of the strong nuclear force among protons and neutrons, the fifty-six particles of an iron nucleus are more...

Hello, I'm wondering, which force is stronger, SNF or EM, how was it proven that specific force is stronger than the other, and are there actually any cases where the weaker force is actually the stronger one. Thanks for all the help

This isn't a traditional homework question but here goes. I asked my physics tutor (A-Level) how the strong nuclear force becomes repulsive at small distances and he said he didn't know. I know that it is a nessecity that it is repulsive to prevent the nucleus collapsing, but I would like to...

Does anybody know if the nuclear force microscope exists, where one could remove or put 1 nucleon at a time into an exisiting nucleus ? (using the same principle as AFM should be too gross...since the tip can not, at my knowledge..be made of one nucleon...maybe an electromagnetic coupling that...

Nuclear forces are said to be non-central. By definiton of central force, angular momentum is constant. It is usually found in spherical bodies. How do the electric quadruple moments indicate the non-spherical structure of the nucleus? How is the nucleus stable if the angular momentum is not...

Whenever i research the weak nuclear force i always get how it is the cause of beta decay and other ways it effects an atom, but i can never get a clear answer to what the force actually is, what does it do? i know that it effects quarks and leptons but i have no idea how it effects them, can...

Thank goodness... ...PF has taught me how to sniff out a crackpot. I was wondering about the strong nuclear force and how it worked and stuff and I thought I should do some research before I posted another incredibly open-ended question here :rolleyes: so I googled "strong nuclear force...

I'm looking for some sort of basic explanation on the characteristics of the weak nuclear force. All of the physics books I've checked up in have only minimal references to the weak force, and the only information I've been able to get on it is a) that it plays some role in radioactivity, and b)...

I have solutions to a past paper essay question that indicates that the student should explain the saturation of the nuclear force in terms of the stability of the helium nucleus. I do not see how to do this, I can only explain the saturation of the force in that the nuclear biniding energy is...

How do we determine the magnitude of the nuclear force acting on the nucleus of an atom?

Great work has been done in the last while on the Four fundamental forces, but is there a fifth ? Is there a Force Number 5 :confused: ? I saw a discussion on this other website http://www.thespacesite.com/community/index.php?showtopic=199 :surprise: QUOTE: the age of the...

how will the potential energy of nucleons decreases with increase in nuclear force

Where can I get the equations that describe the strong nuclear force between quarks/protons/neutrons? Are they not freely available? Thanks.

there are two forces, the nuclear force which binds protons and neutrons together. However as the size of the nucleus gets larger the electrostatic force of repulsion in the nucleus overcomes the strong nuclear force. so larger atoms breakdown to form smaller atoms, why does the electrostatic...

i came across this site http://www.geocities.com/Heartland/6830/evidence.html it gives a list, example... strong nuclear force constant if larger: no hydrogen; nuclei essential for life would be unstable. if smaller: no elements other than hydrogen what do you think?

Hi; I have a question: Does the weak nuclear force convey the decay undergone by radioisotopes or not? Is the decay of radioisotopes caused instead by the electromagnetic repulsion that overcomes the strong nuclear force? Also, what type of radioactivity is conveyed by the weak nuclear force? I...
