When the points were first put into review papers, our papers with my name on them were always quoted. Gradually they got into reviews of reviews and textbooks - the quotation usually was the last review but you could still see the same points. I'd like to have them luminous or something.

The pattern of things was that each of the research students would be doing some particular experiment on the accelerator, often involving the building of counters or a system like that.

One of the good things we did, which was extremely valuable to me, was to make loads and loads of different sorts of Geiger counters.

In 1949 the only way to get out of Sydney was by ship so, with several other graduate students, we sailed off on the Orontes for our great journey.

I had some vague memory of visiting Canberra as a lad, when we came up with my father by car. But when I made the long train journey from Sydney to Canberra and arrived at the little stop, I did wonder slightly whether this really was the national capital.

The Cockcroft-Walton sets were marvellous, rather beautiful machines like a cinematic scientist's dream: tall towers and sparks and so on.

In the tail above the giant resonance, you can get not just one neutron emitted but two, three, four or five, and so there are a lot of things one can measure, looking at the competition with the emission of neutrons and protons and so on.

At that time most photodisintegration work had been with a number of 22 MeV betatrons around the world.

Using the detector which I had brought (along with a few other useful things in my pockets) back to Canberra, I went on with my photodisintegration work, continuing much of what I had done in Cambridge.
