Range Distribution of Alpha Particles Following the Decays ofLi8andB8

The range distributions of the alpha particles resulting from the decays of ${\mathrm{Li}}^8$ and ${\mathrm{B}}^8$ nuclei in nuclear track emulsion have been determined and compared. The range distribution from the decay of ${\mathrm{Li}}^8$ nuclei is found to be similar to that measured by previous investigators and, within statistical error, the range distribution from the decay of ${\mathrm{B}}^8$ nuclei is the same as that found from ${\mathrm{Li}}^8$ nuclei.
