Structure factor for a Bose fluid

KM Khanna, OP Sinha - Physica A: Statistical Mechanics and its …, 1977 - Elsevier
The structure factor is calculated for a Bose fluid using an expression for S (k), which is
approximately valid for all values of k. Marked fluctuations appear for k= 2.15 A ̊-1, near the …
