The nature of the nuclear transformation could be firmly established: the aluminium atom, for example, captures the alpha particle and is transformed, after expelling the proton, into an atom of silicon .

核蜕变的性质因此得到确立。例如，铝原子俘获。粒子，并在排出质子后蜕变成硅原子。

But the positive electrons produced by aluminium under the action of a source of alpha rays continue to be emitted for some time after removal of the source. The number of electrons emitted decreases by half in three minutes.

Fifteen years later, by bornharding with alpha rays certain of the lighter atoms, nitrogen and aluminium for example, Lord Rutherford demonstrated the ejection of protons, or positively charged hydrogen nuclei

15年后他用a射线轰击某些较轻的原子，如氮原子和铝原子，向人们展示质子，即带正电荷的氢核的排斥现象。
