Electrons that are lost from the beam during normal operation of a synchrotron radiation source and during a beam dump at the end of a run produce both ionizing radiation and neutrons. This radiation has the potential of damaging sensitive materials,

We report results from a Dalitz plot analysis of 17750 K e3 0 candidates obtained in an experiment designed to have high efficiency across the Dalitz plot. Assuming a vector interaction form factor ƒ + (q 2 ) = ƒ + (0) (1 + λ + q 2 /m π 2 ) we ob

We report results from a Dalitz plot analysis of 16 386 K μ3 0 candidates obtained in an experiment with high efficiency across the Dalitz plot and very low background. We measure the vector and scalar from factors and obtain the following values fo

The performance of the SLAC 2-m streamer chamber is evaluated using the results of a high-statistics, multibody-photo-production experiment carried out with an 18 GeV bremsstrahlung beam. The instrumental arrangement is outlined, and the data-analysi

We report experimental evidence for a spin of 32 and negative parity for the Y1*(1660), based on a study of a production experiment, K−p→Y1*(1660)++π−→Σ±π∓π±π−, in the region 2.1 to 2.7 GeVc. The spin was determined by an Adair ana

A sample of 6665 annihilations of the type p (at rest)p → π + π − π + π − is analyzed. Mass and angular distributions are given. A maximum-likelihood analysis is made which uses interferring Bose-symmetrized amplitudes to parametrize the re

The reaction γp → π+π−π+π−p has been studied using the SLAC 2-meter streamer chamber placed in an 18 GeV bremsstrahlung beam. We find evidence for a broad enhancement (ϱ′) in the 4π mass spectrum at a mass of 1620 MeV with a width of a
