"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...
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...
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...
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
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?
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
