The purpose of this paper is to study the shell effects
in a dilute interacting fermionic gas trapped in a
3-dimensional harmonic oscillator. The expressions of
the variance of the oscillating part of the energy will
be studied within the taumin - approximation, a semiclassical
model based upon periodic orbit theory, where one
separates the total expression into a regular and a
chaotic contribution. These results will be compared
with the outcome from the Hartree-Fock procedure and
the explicit expressions for two periodic orbits.
