• The limitation of an angular measurement of scattered ions with the use of the “perfectron” has been investigated by means of a computer simulation for a collision energy of ions from 10 eV down to a thermal energy. It turns out that there exsists a certain angular region through which the ions of interest can not be detected in the shade of the detector itself, if a detector of finite geometrical diameter is employed. On the measurement of angular distribution, such a dead angular region is undesirable and should be made as small as possible. However, the computer simulation shows that the effect of this dead angular region is not so serious for energies of usual collison experiments so far as the diameter of the detector is not too large. The minimum permissible energy, above which the exact angular distribution can be measured, is estimated as 10 meV for He+ ions when the detector of 2 mm in diameter is employed.
