consider a particle in one dimention. there is a dirac delta potential such as V=-a delat(x)(adsbygoogle = window.adsbygoogle || []).push({});

the wave functions in two sides(left and right) are Aexp(kx) and Aexp(-kx) respectively.

so the differential of the wave functions are not continious at x=0. what is the justification here?
