THE COLLECTED PAPERS OF LORD 

 RUTHERFORD OF NELSON, O.M., F.R.S. 



VOLUME II 



SIR JAMES CHADWICK, F.R.S. 



Volume II takes the story into his Manchester period, during his time as 

 Professor of Physics, from 1907 to 1919. Here one of his main interests was the 

 atomic nucleus and the a particle. All aspects of his work in this field, which 

 was a lifelong preoccupation for him, are covered. There are papers he wrote 

 with Geiger, concerned with the method for mounting a particles, studies which 

 Geiger pursued further on his own. Other papers deal with the action of the 

 particles on different substances, the probability variations in their distribution, 

 the effects of their collision with light atoms. 



Interrelated with this there is his research into the nature of the radioactive 

 elements, covering a great amount of work on the analysis of their decomposition 

 products and the radiation they emit. 



This volume, like the first one, is a rich source for those who would wish to 

 follow the workings of a rare and lucid intellect. Like Volume I it is worthily 

 produced and illustrated with contemporary photographs and reproductions of 

 Rutherford's apparatus.
