Isotopic Spin and New Unstable Particles
The experimental verification of the static magnetic interaction (a) was made by the g determination of the 0.0gpsec state of Cd"'.' The presence of the static quadrupole interaction (b) was indicated by the correlation measurements on single crystals of In 2 and also by the results obtained with liquid sources. '4 The influence of the randomly fluctuating interactions (c) and (d), such as must...
متن کاملIsotopic Spin and Mass Quantization
In the sessions devoted to quantum electrodynamics it has become clear that the theory of the electron and its electromagnetic interaction is at the moment in good shape, in the sense that there is hardly any direct experimental indication for the need of improvement, let alone for the direction in which modification of the theory should be sought for. It is true that the divergent character of...
متن کاملNucleon resonances and processes involving strange particles
An existing single resonance model with S11, P11 and P13 Breit-Wiegner resonances in the s-channel has been reapplied to the old πN → KΛ data. It has been shown that the standard set of resonant parameters fails to reproduce the shape of the differential cross section. The resonance parameter determination has been repeated retaining the most recent knowledge about the nucleon resonances. The e...

must then consider either the absolute value of the C"(p,pl) cross section or that of the AP7(p, 3prs) cross section (or both) to be in error. We have rather arbitrarily chosen to base our data on the 10.8-mb value for the AP'(p, 3prs) cross section at 420 Mev. Figure 1 shows that the cross section of the C"(p,pcs) C" reaction is a fairly insensitive function of the energy of the incident proto...
متن کاملFOPI Trigger: Improving Statistics on Strange Particles
Introduction. FOPI experiments produce low statistics with respect to certain strange particles, especially negatively charged kaons [1]. The reasons are their rareness and the slow data read-out even with the updated FADC scanning system [2]. Thus, a trigger system is required to ensure that only events containing these particles are read by the FADC scanners [3]. We have investigated, how our...
