Nuclear Scattering & Spin

The contribution of Spin to the depth of the Nuclear Potential

Hitting the broad side of a barn just got a lot harder.

Thankyou. A very nice presentation.

We know that singlet interaction is much weaker than the triplet interaction. Can you please tell me how is the larger cross section in the singlet scattering is related to strength of singlet interaction----- how come weak interaction have larger cross section

[@osmanfb1]

thanks for the usual nice video. Is there a theoretical calculation showing s=0 sigma term to be about 64 ?

Where exactly did we leave out the s=0 state for the potential?

I am reminded with this video of something that has always been for me a curiosity at best or worse, a source of confusion. Why is there so much inconsistency in the units used to describe the properties one thing vs. another? In this case area of a cross section. I would better appreciate cross section in this lesson were it expressed in micron or mm perhaps rather than Barns. I suspect in many cases it has something to do with the person discovering or describing a phenomenon for the first time? Or perhaps I am missing an obvious point or necessity. It makes better sense to my thick skulled learning to stick with the same units whenever possible. That would save many the time required to convert to a unit we are more familiar with. Would it not? Love your lessons and thanks for taking the time and effort to share your knowledge.

Tha barn unit specifically originated during WWII in the Manhattan project as some physicists wanted a term that was secretive and unknown to foreign countries to describe the cross section of a uranium nucleus.

It occurs to me that I don't know what the energy source of spin is, we know all particles have spin and all particles can be described by the wave equation, then I realised the energy must come from the Higgs field?

What is going on in this video?
