The Coulomb dissociation process, induced by the intense source of quasi-real photons acting as nuclear particles pass through the field of a heavy nucleus, has attracted a great deal of attention. As a specific application, and as a means of access to the time-reversed radiative-capture reactions, which are of astrophysical interest at stellar energies, this process provides several.

Radiative neutron capture cross-sections for the isotopesBa,Ce,Ce,Nd,Nd,Gd,Ho,Hf,Ta,Os,Au andHg have been measured at the neutron energy (23±5) keV by means of the activation method and 4π-geometry gamma-counting technique.

Pi mesons, also known as pions, consist of a quark and an antiquark and are extremely unstable. Neutral pions have a lifetime of only ∼80 attoseconds, decaying into two photons. Quantum chromodynamics (QCD), the theory of quarks and gluons, predicts this decay and the associated lifetime using the mechanism of broken chiral symmetry—the so-called chiral anomaly.

The energy spectra of neutrons emitted following muon capture in 16 O and 12 C are investigated using the continuum shell model. Nuclear wave functions, which have been shown by Ohtsubo and the author to describe the radiative pion capture reaction in the above nuclei well, are adopted.

The latter has been observed only with hydrogen and 3 He targets. Measurements of the photon spectra from hydrogen and deuterium targets in the early s helped determine basic properties of the pion, such as its mass, odd intrinsic parity, and the π-N coupling recent years targets ranging up to A = have been studied and much of the interest has turned to the use of.

This volume consists of twelve review articles and a variety of short contributions which are based on lectures presented at the International Symposium on Photopion Nuclear Physics.

The review articles were submitted after the sym­ posium, and there was considerable editing and cross referen­ cing.

In-flight radiative capture cross sections have been studied for the process 15N(π+,γ)15O(g.s.). Total and differential cross sections have been calculated, and the effects of pion distortions.

We have calculated the rate for radiative pion capture from a ls atomic orbital in the π −3 He→γ 3 H analog transition. The nuclear model result utilizing the impulse approximation agrees essentially with the particle model result.

Combining this rate with our estimate of the π −3 He→π 03 H rate, we obtain a Panofsky ratio P 3.
