The {sup 114}Cd({alpha},xn) reaction has been studied for E{sub {alpha}}=35-55 MeV following neutron emission and {gamma}-ray deexcitation. Excitation functions of various ({alpha},xn) channels measured from {gamma}-ray yields have been compared with theoretical calculations based on ALICE-91 and CASCADE codes. Neutron energy spectra were generated from {gamma}-gated neutron time of flight spectra. Neutron energy spectra corresponding to ({alpha},3n) and ({alpha},4n) reactions at E{sub {alpha}}=50 MeV have been theoretically reproduced taking into account the contributions of equilibrated source with level density parameter a=A/11, along with the contributions from the pre-equilbrium process.
