Homework Statement
Hi...
I think I might be staring blind at this one.
I have to calculate the theoretical halflife for the ground state alpha-decay, and compare it to the experimental value.
What is know is that the nuclei [itex]Sm^{147}_{62}[/itex] decays by the emission of a alpha-particle to the ground state of [itex]Nd^{143}_{60}[/itex] with a branching ratio of 100%. The two ground states have same spin and parity. The [tex]Q_{\alpha}[/tex]-value is 2.311 MeV.
Homework Equations
Not sure tbh...
<tex>t_{1/2} = \frac{\ln (2)}{\lambda} = \tau \ln(2)</tex>
The Attempt at a Solution
I dunno... I'm missing something, or then it is just very very simple :/
So I was kinda looking for a hint or something :)
Regards.
