well you could have $s_{max} = 5/2$ and $s_{min} = 3/2$ with no more in between. both of which are half integer spins - so a fermion. either way you cut it, if anyone value of total spin is an integer (half-integer), the rest have to be integers (half-integer) so no ambiguity between bosons and...

an atom consists of an electron (spin 1/2) and a positively charged spin 2 particle at the nucleus (in place of the proton). is this 'atom' a boson or a fermion?

sorry, that was what i meant-a v-shaped potential well

anyone happen to know how to estimate the ground state energy of a vee-box using the uncertainty principle?

hi, if we have a potential of the form V(x) = a|x|, how would one go about estimating the ground state energy of the system using the Heisenberg uncertainty principle. I suppose the thing to do is to get an estimate of delta x, then get delta p via the Heisenberg uncertainty principle and...

hi, if an operator O has the property that O^{4}f(x)=f(x), what are the eigenvalues of O? any hints on how to go about this?

Hi all, I was wondering if someone could help me out on this (taken from Newtonian Mechanics, A.P. French, pg 705, problem14-23) A wheel of uniform thickness , of mass 10kg and radius 10cm is driven by a motor through a belt. The drive wheel on the motor is 2cm in radius. The motor is...

is the pivot point moveable? (i.e. does d=d(t) or does d=const)
