Nuclear Physics

The tremendous strides made in the last four years in the field of Atomic Physics were summarised by Mr. C. N. Watson-Munro and presented to the Maths. and Physics Society on July 28, in a paper entitled "Recent Advances in Nuclear Physics." Beginning with the positron, the lecturer described its discovery and characteristics. He then similarly described the neutron, mentioning particularly the work of Bothe and Becker in Germny, of Curie and Joliet in France, and of Chadwick in England. The purely mathematical conceptions, the neutrino and antineutrino were then considered and the diplon, or heavy hydrogen nucleus was described, Artificial radio-activity, and the transmutation of the elements were discussed, and the lecturer then gave a summary of the characteristics of the different particles already described, concluding with an account of the recent work done in the determination of "e."

After a hearty vote of thanks had been accorded the speaker, the meeting adjourned to an excellent supper kindly provided by Mrs. Florance.
