THEORICAL FORMULAE OF (n, 3 He) REACTION FUNCTION EXCITATION AT 14?6 MeV
excitation at 14.6 MeV, this semi-empirical systematic reduces parameters taken in previous
proposed formulae which increase the contribution of pre-equilibrium 3 He particle emission. We
use exciton model in closed form and coalescence model to describe the pre-equilibrium 3 He
particle emission in reaction induced by neutron. To check the formula’s quality we compare
obtained cross section with measured ones. The formula obtained in this work has a good fitting
with lower values of statistical parameters.

Isotopic effects in the He+ - He collision at lower energies.
He(1s), when both species are in their ground states, are either gerade (g) or ungerade (u), namely, 2Σ+g or 2Σ+u
in the field of energy 10−12 ≤ E ≤ 10−2( a.u.), using new and modern data. Elastic cross-sections have also been
calculated and the isotope effect of the presence of 4He and 3He atoms has been addressed, taking into account the
nuclear spin and analog effect emanating from similar and non-distinction between colliding atoms.

quantum mechanically within the Chapman-Enskog approximation [1]. The calculations start by
constructing the ion-atom potentials in the short-range, intermediate, and long-range regions. The
appropriate dispersion coefficients are adopted. An example of the generated potential-energy

with other calculated potentials.
The potentials are further used to solve the radial wave equation and therefore to determine
the phase shifts needed in the computation of the collision integrals and the coefficients of
diffusion and mobility. The variation law with temperature of both coefficients is examined and
the results show that the diffusion coefficients vary like ~aTb

coefficients of sodium and potassium ions diffusing in ground helium gas are presented in Fig 2.
Particularly, the results of the reduced mobility, at given temperatures and pressures, can be
compared with published values in case of very week electric field in the Table below.

the range of low and high temperatures, with new and recent potential data points. The
classical second virial coefficients are computed in order to assess the accuracy of the
constructed He-He potential. The results, mainly at high temperatures, are in a good
agreement with the published values. The isotopic effects due to the presence of 4He and
3He atoms are also examined and the calculations of various transport parameters, namely
diffusion, viscosity, and thermal conductivity, are extended to include the nuclear spins
and the symmetry effects, which arise from the identity and indistinguishability of the
colliding atoms.
