Abstract：
In heavy ion feaction mechanism experiment,a phoswich array consisting of 20 ΛE-E elements has been used for the measurement of light charged particales emitted at forward angles.The full angular coverage is θ_L±20°,φ_L±9°,Different α-particle energies were obtained by degrading the beam with aluminium foils of appropriate thickness for energy calibration.Our experimental data were fitted well by using a fairly simple expression.The obtained α-particle energy spectrum is in good agreement with that,measured by a sillicon by a silicon detector telescope.
