WebThe possible wave functions are ψ = ψa(x1) ψb(x2) ψc(x3), There is no symmetrization requirement. (b) If the particles are identical fermions only one state can be constructed. The wave function must be anti-symmetric under exchange. Notation a, b, c>: Let a denote the state of particle 1, b the state WebSymmetric wave function solutions are shown by a certain class of particles, known as BOSONS, and they do not follow the Pauli's Exclusion principle.

Fermion -- from Eric Weisstein

WebThe treatment of fermion wave functions in their antisymmetric form in terms of what is now called Slater determinants was developed by Paul A. M. Dirac in a famous 1926 paper, where he writes: An antisymmetrical eigenfunction vanishes identically when two of the electrons are in the same orbit. http://electron6.phys.utk.edu/PhysicsProblems/QM/8-Identical%20particles/counting.html the eiffel shower

WebComment: There’s a cute trick for constructing completely antisymmetric wave functions: Form the Slater determinant, whose first row is ψa ( x1 ), ψb ( x1 ), ψc ( x1 ), etc., whose second row is ψa ( x2 ), ψb ( x2 ), ψc ( x2 ), etc., and so on (this device works for any number of particles).
