Measurement of the Lamb Shift in Muonium.
Abstract
This thesis describes the first measurement of the Lamb shift in n = 2 muonium. The muonium atom is a hydrogenlike bound state of two leptons ((mu)('+)e(')), both of which are believed to be pointlike particles. The pointlike nature of the constituent particles simplifies and reduces the uncertainty of the application of quantum electro dynamics (QED) to the calculation of the Lamb shift in the muonium atom. Measurements of the Lamb shift in hydrogen disagree with the predictions of theory by a few standard deviations; however, theo retical predictions also disagree with each other, partly because of difficulties associated with the treatment of the proton structure. Thus a measurement in the muonium system of similar precision to those already made in the hydrogen system will be a valuable test of QED. This experiment is an investigation of the methods and tech niques necessary to surmount the difficulties presented by the nature of muonium. The available number of muonium atoms is about 10('+10). times less than that of hydrogen used by Lamb in his first measure ment. The value obtained for the n = 2 muonium Lamb shift.
