Experimental Search of Structures in Missing Mass Spectra of B = 2, T = 1 System: Possible Evidence for Narrow States

摘要

The missing mass spectra for the transfer reaction p( sup 3 He,d)X (B = 2, T = 1) have been measured at Tsub( sup 3 He) = 2.7 GeV. The data show: 1) a narrow structure lying on top of an important continuum, with a mass M = 2.240 +- 0.005 GeV and a width GAMMAsub(1/2) = 0.16 +- .003 GeV; 2) a large structure with centroid location close to Msub(x) approximately equal to 2.170 +- .005 GeV and width GAMMAsub(1/2) approximately .100 +- .005 GeV.
