✦ Synopsis

Rotationally inelastic cross sections have been calculated according to a quantat static rotation (sudden) approximation and the quasiclassical method for 4He + If(j = 12) (rigid rotas) at an ioitial relative kinetic energy of 0.M eV_ Comparison of the two sets of results shows excelient agreement. In addition, normaiizeQ static rotation results we in cxceilent agreement with experiment.
