    Attractive nature of nuclear forces

    "At a distance of 1.5 fermi, the nuclear force becomes maximum and remains attractive in nature. However, at a distance of 0.5 fermi, the nuclear force suddenly becomes repulsive. " Revered Members, Nuclear force is a short range force, so naturally when the distance between the nucleons...

    Nuclear Binding Energy

    Revered Members, For Helium, Beryllium,Carbon,Oxygen and Neon, the Binding Energy per nucleon is more as evident from the sharp peaks observed in the graph plotted between BE and Mass number. These elements have equal number of protons and neutrons. When there is an inequality between proton...

    Binding energy per nucleon

    From the graph plotted between Mass Number and Binding Energy per Nucleon, we infer the BE/A is stable for mass numbers between 20 and 60 (approximately) and decreases for A>60. Similarly the BE/A is very less for lighter nuclei, say, Helium. Nuclear forces are short range forces. So it is...

    Cluster radioactivity - preformed cluster model

    Thanks again Mr. Sam. Do cluster radioactivity comes under the category " Strong interaction"?

    Cluster radioactivity - preformed cluster model

    Thanks a lot Mr. Sam for your reply. You said "cluster rattling around inside the parent". I construe this as the time taken by the cluster or attempts made by the cluster to come out of the parent nuclei. Am i correct?

    Cluster radioactivity - preformed cluster model

    cluster radioactivity --- preformed cluster model In cluster radioactivity, heavy nuclei decay to form Helium, Carbon, Nitrogen, Silicon etc. I came across the term Preformed cluster model. What is preformed cluster model? Members, could you please throw some light on this?

    Electrons not inside the nucleus?

    Thanks a lot mr. jtbell, zapperz and physeven. actually mr. jtbell have correctly interpreted my question, though my question is ambiguous. heisienberg uncertainty principle is del p, del x >= h/2 pi. am i correct? some textbooks say it is >= h/4 pi

    Electrons not inside the nucleus?

    an unstable neutron decays to electron, proton and anti neutrino. if that being the case, why electrons are not inside the nucleus?
