Two spin zero identical bosonic particles of mass m are in an 1d infinite square well potential of width a. the particles interact weakly via the ô-function potential u(x, x2)-auo 5(x-x2), where x is the coordinate of the particle number j, and uo is a constant of interaction (that is the particles don't like to be on top of each other, repulsion for positive uo) (a) first, ignore the interaction and find the ground state and the first excited state of the two- particle system in the square well potential. construct correct (allowed by nature) two-particle wave functions p? (x, x^) and p^(x,, and find the corresponding energies (b) use the first order perturbation theory to evaluate the effect of interaction on the two-particle system energies of the ground and the first excited states
