Hello All,
I need some explanation on the relative stability of 237-Np and 237-Pu. We know that 237-Np has 2.144x10^{6} yrs of half-life. On the other hand, 237-Pu , which has only 1 extra neutron as compared to 237-Np has a half-life of 45.2 days with EC and alpha as most prominent decay modes.
Can we explain as to how does this additional neutron makes the nuclide less stable. The number of neutrons is 145 for 237-Pu as compared to 144 for 237-Pu, and these are not magic numbers as well.
How can we explain this fact.
any answers would be useful
thanks
