چکیده
The NA48 collaboration has measured the amplitude of the CP-conserving component of the decay K0 S → π+π−π0 relative to K0 L → π+π−π0. For the characteristic parameter λ, the values Re λ = 0.038±0.010 and Im λ = −0.013±0.007 have been extracted. These values agree with earlier measurements and with theoretical predictions from chiral perturbation theory.

This paper is meant as a contribution to the often debated subject of how to combine data which appear to be in mutual disagreement. As a practical example, the ǫ ′ /ǫ determinations have been considered.

A search for the decay KS → π0γγ has been made using the NA48 detector at the CERN SPS. Using data collected in 1999 during a 40-hour run with a high-intensity KS beam, an upper limit for the branching ratio BR ( KS → π0γγ, z ≥ 0.2 ) < 3.3× 10−7 has been obtained at 90% confidence level, where z = m2γγ/m2K0.

Direct mass measurements of short-lived Cs and Ba isotopes have been performed with the tandem Penning trap mass spectrometer ISOLTRAP installed at the online isotope separator ISOLDE at CERN. Typically, a mass resolving power of 600 000 and an accuracy of m 13 keV have been obtained. The masses of Ba and Cs were measured for the rst time. A least-squares adjustment has been performed and the e...

An ion beam cooler and buncher has been developed for the manipulation of radioactive ion beams. The gaslled linear radiofrequency ion trap system is installed at the Penning trap mass spectrometer ISOLTRAP at ISOLDE/CERN. Its purpose is to accumulate the 60-keV continuous ISOLDE ion beam with high e ciency and to convert it into low-energy low-emittance ion pulses. The e ciency was found to ex...
