The bremsstrahlung emission due to collisions of nonrelativistic electrons with chains of strongly coupled dust grains in a plasma is investigated in dusty plasmas. The dust chain is considered as the one-dimensional model for strongly coupled dusty plasmas. The Born approximation is assumed for the initial and final states of the projectile electron and coherent effects are considered. The result shows that the radiation cross section is greater for smaller dust spacing for soft photon regions. This work shows a possibility of the low energy continuum radiation due to the electron-dust-chain collisions in dusty plasmas. © 2003 American Institute of Physics.
