Abstract
It is shown that the energies and widths of resonances can be determined from the discrete states calculated in a spherical box. The variation of the radius of the box exhibits clearly the positions as well as the widths of the resonances. Two formulae are given to calculate the resonance width using only the energies of the discrete states as a function of the radius. The approach is exemplified by two model problems.Keywords
