We describe the measurements of neutron and charged particle production double differential cross sections (DDXs) from 15-$$mu$$m-thick $$^{9}$$Be and 1-$$mu$$m-thick $$^{rm nat}$$Fe targets bombarded with 13 MeV/nucleon $$^{20}$$Ne and comparisons between the experimental data and calculation results. The target was installed in a vacuum chamber. For the neutron measurement, the NE213 organic liquid scintillators were placed at a distance of 2.0 m from the target. For charged particle measurements, the telescope detectors composed of three Si strip detectors (SSDs) with different thickness were placed in a vacuum chamber. For neutrons, the calculated results generally overestimated the measured data due to the emission of many neutrons following the decay of excited fragments with high energies. For tritons, calculated results at 30$$^{circ}$$ give good agreement with the experimental data, while that at 90$$^{circ}$$ gives large underestimation.
