J. D. Bowman,M. D. Cooper,M.E. Hamm,C. M. Hoffman,R. E. Mischke,D. E. Nagle,J. S. Sarracino,P. A. Thompson,Herbert L. Anderson,W. W. Kinnison,H. S. Matis,S. C. Wright,R.L. Carrington,R. A. Eichler,R. Hofstadter,E. B. Hughes,T.P. McPharlin +16 more
TL;DR: An examination of 3.6 and 3.9 is the upper bound for the branching ratio with 90% confidence as mentioned in this paper, where the latter is an improved upper bound of 1.9.
Journal ArticleDOI
Search for. mu. /sup +/. -->. e/sup +/. gamma
W. W. Kinnison,Herbert L. Anderson,H. S. Matis,S. C. Wright,R.L. Carrington,R. A. Eichler,R. Hofstadter,E. B. Hughes,T.P. McPharlin,Judd D. Bowman,Cooper,M.E. Hamm,C. M. Hoffman,R. E. Mischke,D. E. Nagle,J. S. Sarracino,P. A. Thompson +16 more
TL;DR: In this article, a kinematically complete search for the muon decay was performed using a magnetic spectrometer outfitted with proportional chambers to measure the positron momentum vector and a large segmented NaI(Tl) array to determine the gamma-ray energy and impact point.
Journal ArticleDOI

TL;DR: The Cluster of 54 detector as mentioned in this paper is the predecessor of the Crystal Ball detector, which is designed for the study of electron-positron collisions at colliding beam facilities, and it has been successfully tested.
Journal ArticleDOI
On the detection of 50 MeV γ-rays with a large modularized NaI(Tl) detector
R.L. Carrington,R. A. Eichler,R. Hofstadter,E. B. Hughes,J. Rolfe,T.P. McPharlin,J. D. Bowman,M. D. Cooper,M.E. Hamm,C. M. Hoffman,R. E. Mischke,D. E. Nagle,J. S. Sarracino,P. A. Thompson,Herbert L. Anderson,W. W. Kinnison,H. S. Matis,S. C. Wright +17 more
TL;DR: An array of 45 NaI(Tl) crystals modules, each in 20 in. in length and hexagonal in cross section with six 3 in. sides, has been operated as a detector of 50 MeV γ-rays in a search for the decay μ + →e + γ as mentioned in this paper.
Journal ArticleDOI

A. Johansson,B. L. Beron,L. E. Campbell,R. A. Eichler,P. Gorodetsky,R. Hofstadter,E. B. Hughes,S. L. Wilson +7 more
TL;DR: The coded aperture, a refinement of the scatter-hole camera, offers a method for the improved measurement of γ-ray direction in γray astronomy as mentioned in this paper, and two prototype coded apertures have been built and tested.
