We apply the discrete dipole approximation method and a model of random irregular particles. Our results confirm water ice composition of the cm-sized chunks detected by the NASA Deep Impact space probe in the vicinity of the nucleus of Comet 103P/Hartley 2. The index of the power-law size distribution in this case can be constrained to the range n ≈ 3.3–4.3. For the other considered comets the circular polarization ratio can be reproduced with variations of the power index between 2 and 5."],"language":["eng"],"type":["info:eu-repo/semantics/article","doc-type:article","text","http://purl.org/coar/resource_type/c_6501"],"subject":["tet_topic_scattering","ddc:530"],"rights":["info:eu-repo/semantics/openAccess"]},"department":[{"_id":"61","tree":[{"_id":"3"},{"_id":"34"},{"_id":"44"},{"_id":"43"}]}],"dini_type":"doc-type:article","publication_identifier":{"issn":[]},"publication_status":"published","intvolume":" 608","_id":"3523","urn":"35230","citation":{"ieee":"S.
