  UKRmol+ is a new implementation of the UK R-matrix electron-molecule
scattering code. Key features of the implementation are the use of quantum
chemistry codes such as Molpro to provide target molecular orbitals; the
optional use of mixed Gaussian -- B-spline basis functions to represent the
continuum and improved configuration and Hamiltonian generation. The code is
described, and examples covering electron collisions from a range of targets,
positron collisions and photionisation are presented. The codes are freely
available as a tarball from Zenodo.
