Nevertheless, it turns out that the shape of the energy spectrum is largely determined by the increase in the particles energy and the decrease in their number as radiation sources are removed from the Earth.

In order to study the energy spectrum of shallow donor confined in volcano-shaped InAs/GaAs QR, taking into account strong nonparabolicity of the InAs conduction band, we use below a simple version of the Kane model, proposed in [23, 24].
There will be the well-known nonrelativistic energy spectrum as [E.sup.(1).sub.n,m] = ([lambda] + [gamma] + n + m)(m - n - 1) and [E.sup.(2).sub.n,m] = (2[lambda] + n + m)(n - m + 1) for Poschl-Teller potential and Scarf-II potential, respectively.
