Bound state of particle in delta-potential in tomographic representation of quantum mechanics

The problem of quantum particle moving in Dirac delta potential with instant changing well depth is studied by using formalism of tomographic representation of quantum mechanics.The bound state tomogram is given in terms of error function.The ionisation probability due to instant change of the potential parameter is calculated in terms of integral containing the state tomograms.The probability of ionisation is also expressed in terms of the Wigner function.
