ABSTRACT
The chapter presents the results of experiments on the transformation of beryllium and boron by protons and by ions of heavy hydrogen. Authors concluded, therefore, that they were hydrogen nuclei, and since the supposition that they were protons appeared unlikely authors suggested the nuclear transformation as the simplest hypothesis, despite the fact that be was not known to exist in nature. The energy balance in the above transformations is discussed later in this paper. However, they have seen that for beryllium and boron no such agreement can be found. In the course of our work we believe we have found clear evidence of the existence of two new isotopes of beryllium of masses 8 and 10. As a result of the study of nuclear transformations all mass-numbers in the first part of the periodic table have been filled except 5.
