Excitation functions for eight reactions of the type169Tm(α, xn),x=1 − 4;169Tm(α, pxn),x=3; and169Tm(α, αxn),x=1, 2, 4 were investigated. Of these, four reactions169Tm(α, p3n),169Tm(α, αn),169Tm(α, α2n)169Tm(α, α4n), were studied for the first time and in the remaining four reactions, some 19 new energy-point cross-sections were measured for the first time. The experimental cross-sections were compared with the predictions of pre-equilibrium hybrid model, as well as the more recent index model, using the initial excition number,n 0=4 (4p0h). Both the models show better agreement in respect of (α, xnyp) type of reactions. However they are equally bad for (α, αxn) type of reactions which involve theα-particle in the exit channels, and for which some direct reaction contributions are indicated.
