OK - the question gives me two bosons with 0 spin (and the wavefunctions/energy levels) and tells me to find the total wavefunction and energy for the ground state and first excited state. Now, I know the total wavefunction must be symmetric. I know the symmetric spatial part. But the spin part, i'm having some problems with. There is only one spin state (since s=0), correct? Now what I do not understand is: - What is the spin state for s=0? - Is this spin state symmetric or antisymmetric? - Does the spin state change going from the ground to the excited state? - How do I combine it with the spatial part? Just multiply the two together? Sorry for the many questions but I can't find any of this in my book, it pretty much skips the role of the spin part altogether.
