We extended a previous study on the role of polarization effects in the positron-allene scattering and also present some preliminary results for positron collisions with cyclopentane. We also compare the differential cross sections of benzene and its azaderivative pyrimidine at selected energies, where similar angular behaviour was found.2616694engGeneral Physics and Astronomyjournal article10.1088/1742-6596/1412/5/052001https://www.scopus.com/pages/publications/85086638458
