Can we get continuous energy spectrum of Schrödinger equation in numeric calculations?

Solving Schrödinger equation numerically we will have finite size matrix, which has finite number of eigenvalues, that is - discrete spectrum. But we know, that atoms also have continuous...

Does discrete mechanics have Hamiltonian?

Imagine that we have point interacting particles, that moving according law like x(i, t+dt)=x(i,t)+f(i,j,t)*dt. Or also velocities can be included. In the limit dt ->...

Is there any analytical expression for wave function in the case of potential well and finite barrier like in alpha decay?

We believe, that alpha particle goes out of nuclei with probability ~exp(-gamma*t), but this is only asymptotic formula. Can we choose some potential, where the formula will be "exact"?
