[en] The γ-decay following the ²⁷Al(tau,α), ²⁷Al(tau,tau) and ²⁷Al(tau,t) reactions has been studied using Esub(tau) = 45 MeV. For all three reactions a maximum mean γ-ray multiplicity of < Msub(γ)> = 1.8 +- 0.2 is observed in good agreement with the Fermi gas model. The variation of < Msub(γ)>with excitation energy for the ²⁷Al(tau,tau)²⁷Al reaction, however, shows considerable deviations from the decay pattern expected for a statistical system. From a comparison with other reaction channels, it is suggested that the selectivity in the excitation of states in the inelastic process is responsible for this non-statistical pattern
