nobody help me ?

In a system with two spin 1/2 particles , We now ask what are the allowed total spin states generated by adding the spins ${\bf S}= {\bf S}_1 + {\bf S}_2$ ,in fact, they are Singlet and Triplet Spin States \left( \begin{array}{ll} |1,1\rangle & =\uparrow\uparrow\\ |1,0\rangle &...

i have the same question,and still cannot understand the concept, what is coulomb barrier? just like what seerongo said, "any barrier that must be overcome by an alpha trying to escape would derive from the dominance of the strong force, binding the alpha to the nucleus, over the Coulomb force...

can you tell me how to prove the second formula according to the first formula in the attachment?

nobody give me some recommendations?

thanks , but i still cannot understand it

The nuclear electric quadrupole moment is a parameter which describes the effective shape of the ellipsoid of nuclear charge distribution. A non-zero quadrupole moment Q indicates that the charge distribution is not spherically symmetric. By convention, the value of Q is taken to be positive if...

F=-\nablaV i cannot fully understand it ,though i can deduce it in some ways. i also want to know why potential energy is so extensive and important.

thanks

recently,i am focusing on studying the nuclear model, can you recommend some articles ,good review and Classic books about nuclear model,especally the cluster model to me? thanks
