抜粋

The partial wave analysis is an important method of obtaining the collision cross section in atomic and nuclear physics. An algorithm is devised to reduce the computing time by using a vector computer. In solving the Schrödinger equation numerically, this algorithm vectorizes the recurrent calculation in an ingenious way. The method is suited for those problems that are related to relatively a small number of quantum states (reaction channels). A simple example of the calculation is shown for elastic scattering. A speed-up gain of 8 is achieved in comparison to a scalar computer.
