Which of the following states isare antisymmetric there may

Which of the following states is/are antisymmetric (there may be more than one): the joint spin state of two electrons that has total spin $ = 1 and magnetic quantum number m_s = 1 the joint spin state of two electrons that has total spin.s = 1 and magnetic quantum number m_s = 0 the joint spatial state of two electrons that has total spin s = 1 and magnetic quantum number m_s - 1 the joint spatial state of two electrons that has total spin s = 1 and magnetic quantum number m_s = 0

Solution

spin state has to be a singlet since it is antisymmetric .since total wavefunction must be antisymmetric.

The spin and magnetic quantum number for singlet state is s = 0 and m = 0
