1. Centenary of particle pioneer Philip Ball SUMMARY: Cecil Powell won Nobel for discovering the pion and firing up a new field of physics. CONTEXT: ...in its tracks and spawn another kind of meson. Powell's team called the first a pi meson (pion) and the second a mu meson (muon). The muon turned out to be the same as the mesons seen before. But the pion was something new: a...

Nishiizumi, J. Klein, R. Middleton, H. Craig CONTEXT: ...by underground mining at depths exceeding a few metres the cosmogenic production will arise primarily from fast mu-meson interactions5. This production rate drops by more than three orders of magnitude at pressures exceeding 3 x 103...

Production of 10Be and 26Al by cosmic rays in terrestrial quartz in situ and implications for erosion rates K. Nishiizumi, D. Lal, J. Klein, R. Middleton, J. R. Arnold CONTEXT: ...is caused by nuclear spallation of Si and O, and the 26A1 is caused by nuclear spallation of 28Si and negative mu-meson capture in 28Si. Other contributions to the production of 26A1 and 10Be from in situ radioactivity are...

Panofsky CONTEXT: ...little account of the impact of the major experimental discoveries.- remember, for instance, the upset when the mu meson turned out not to be the carrier of the strong interaction predicted by Yukawa.

CONTEXT: ...by B. Pontecorvo in 1968, there were of course only two types of neutrinos, corresponding to the electron and the mu-meson. (Strictly speaking, just as there is an anti-electron corresponding to the electron, so there is an...

One way is to study the X-rays emitted from atoms that have captured a negatively charged mu-meson into orbit. Muons, being heavier than electrons, orbit much nearer the nucleus, and on undergoing transitions emit...
