“…Bonsignori and Selleri had evidently in mind our paper on elastic scattering, Ref. (9) , although they could not have found there an explicit indication as to the nucleon radius having a value "similar" to the Compton wave length of the pion. The cases at hand were offered by single pion production processes in nucleon-nucleon and pion nucleon processes (Fig.…”

“…A mixed Bologna 8 -Trieste 9 group, joined by a visitor, Leo Lavatelli, a John Simon Guggenheim Fellow from the University of Illinois at Urbana, looked at π − + p elastic scattering, and measured its differential cross section. (9) The angular distribution showed an expected forward peak, interpreted as diffraction scattering, and a backward bump. The partial wave analysis showed that terms up to at least F-waves were necessary.…”

The late Fifties were going to be eventful for physics in Italy. CERN had officially started its activities in the fall of 1954; however, the single European countries, Italy in the first place, were not in the condition to compete at the highest international level. A peculiar form of international distribution of the forms of research activities was then going to characterize those years, in particular as far as relationships between Italy and the United States were concerned. Italian physicists who had become known in the United States and were in close relationship with their colleagues active on the opposite shore of the Atlantic obtained that the analysis of data collected in American labs.-in particular bubble chamber data-could be partially carried out in Italy. I try here to give a feeling of the kind of theoretical activity that involved Franco Selleri, among others, in that context.

“…Here, p is the probability that a given event would be detected, which takes account both of the neutral decay mode of the V°'s and of the escape probability; C is the ratio of the number of K~ decays in the reduced film sample (r~ contamination = 0.08=1=0.11%) to the total number of K~ decays, i.e., C corrects for the fact that these V° two-prong events were taken from the whole film sample, whereas the two-prong events were not. By this method, we concluded that 47=1=7 of the events in group P were due to reaction (11) and 54=1=8 in group x + were due to reactions (12) and (13).…”

“…In addition to producing inelastic two-prong events, reactions (10), (12), and (13) also produce V° two-prong events. These V° two-prong events are much less difficult to analyze than the inelastic two-prong events, and they have been studied in de tail , 2,3, The data on these V° two-prong events were used to determine the number of events remaining in group P due to reaction (10) and the number remaining in group ir + due to reactions (1.2) and (13).…”

This paper contains the conclusion of the systematic study of K~p interactions in the Lawrence Radiation Laboratory's 15-in. hydrogen bubble chamber at 1.15 BeV/e. In particular, we report on the elastic and charge-exchange scattering, K*N production, and Sx reactions. The procedure used in scanning, measuring, and computer analysis is described in detail. The similarity of total as well as differential cross sections for the three STT charge states suggests predominant production from the T=0 state for this channel. The angular distributions for the ST reactions, as well as the elastic and charge-exchange scattering, indicate that partial waves as high as F 5/2 must be involved. The analysis of the Krprfi reactions substantiates the earlier preliminary result of isotopic spin 1/2 for the K* resonance. The angular distributions and correlations in the K~pir° and K~ir + n reactions support the conclusion, derived from the previous study of our K°pTT~-events, that the K* spin is 0 or 1. A summary of cross sections for all the reactions studied in the experiment is given.
