Nature of problem:RESTOR 1 computes the phonon spectrum from the incoherent inelastic scattering data of cold neutrons by a polycrystal consisting of identical atoms. | ||

Solution method:A nonlinear integral equation for the phonon frequency distribution in a polycrystal is constructed. This equation is solved by the method of consecutive approximations. | ||

Restrictions:The program is limited to polycrystals with identical atoms. It is assumed that the neutrons are scattered with energy gain. But the program RESTOR 1 provides for the case of scattering with energy loss, when the factor exp(epsilon/kBT} appears on the right-hand side of eq. (4) in the long write-up. | ||

Running time:The time required for the test run is 4 min 30 s on the EC 1030 computer, of which 2 min is taken in compiling. |
