      abstract     = {The HERMES experiment in Hamburg, Germany, consists of a
                      large forward spectrometer which studies various physics
                      processes related to the nucleon and its internal structure.
                      The main focus of the analysis presented in this thesis is
                      based on the angular decay distributions of the decay
                      products of the ρ0 vector meson. By examining the angular
                      decay of the outgoing decay products the Spin Density Matrix
                      Elements (SDMEs) for the ρ 0 can be determined. The
                      extraction of the ρ0 data sample from the raw HERMES output
                      data is explained and the method used to extract exclusive,
                      diffractive ρ0s is given. The analysis procedure and the
                      method used to analyse the data samples is then explained
                      with consideration given to the description of the method
                      used to extract the spin density matrix elements. In the
                      autumn of 2005 a new detector known as the Recoil Detector
                      will be commissioned in the front region of the HERMES
                      experiment. The Recoil Detector will advance the analysis
                      presented in this thesis in some regards, ie the improved
                      t-resolution at low t which will improve exclusive
                      measurements including vector meson production. Several
                      contributions to the Recoil Detector are presented in
                      detail. In particular the research of the HELIX128-3.0
                      readout chip and its development towards the final readout
                      of the silicon detector and the integration of the Recoil
                      Detector into the Hermes Monte Carlo.},
