| Description | Blackett is interested 'in the very beautiful photograph of a mesotron that apparently stopped in the gas, which you reproduced in a recent number of the Physical Review. I would very much like to know what your final conclusion is as to the evidence it provides for (a) the non-existenxe of the expected decay electron of forty million volts, or (b) the existence of some other process by which the mesotron might be absorbed before it had time to decay. If the decay process does not occur it is really extremely interesting to know what does happen to them.
I would be very pleased if you could send me a print of the photograph so as to be able to make a better slide of it than is possible from the reproduction.
I will be very interested to hear if you get any more such photographs.' |
