Constraints on new interactions from neutron scattering experiments

“…for the potential of Eq. (38). The first terms in the brackets correspond to the pointlike potentials of Eqs.…”

“…Significant diffraction effect appears in the neutron scattering by noble gases due to atom-atom interactions [38][39][40][41][42][43]. The static structure factor depends on interatomic interaction potential U (r) and atomic density n:…”

“…Fig.3. The calculated neutron energy dependence of the center-of-mass scattering asymmetry (θ 1 = π/6, θ 2 = 5π/6) from 1 atm pressure Xe gas target in result of different effects: 1 and 2 -n − −e interaction with the values of n − −e scattering lengths -1.32•10 −3 fm and -1.59•10 −3 fm; 3, 4, 5, and 6 -diffraction effect for different approximations of the interatomic Xe-Xe interaction: 3 and 4 -two approximations of Lennard-Jones potential for Xe[38,39], 5 and 6 -potentials of more complicated form from[40]; 7, 8, 9 and 10 -effect of hypothetical potential of the form Eq. (1) for λ equal to 10 5 fm, 10 4 fm, 10 3 fm and 10 2 fm and α equal to 10 23 , 10 25 , 10 27…”

Analysis and Modeling of Spectral Line Shapes of Collision-Induced Light Scattering of Gaseous Xenon

“…The group of Chrysos [4,5] used the relatively recent ab initio calculations of the xenon trace and anisotropy by Maroulis, et al [6]. However, the interatomic potentials used by all these groups for their theoretical calculations were empirical and quite old [7,8]. In this paper, we propose two new potentials based on different sets of experimental measurements.…”
