Abstract
The reaction was studied using 57-MeV protons from the Oak Ridge isochronous cyclotron. The correlated energies of both the emitted protons and particles were measured at detection angles () of (94°, -35.3°), (105°, -30°), and (116°, -25.1°), where the detectors were coplanar with the beam. In addition, an angular correlation was measured by fixing at 105° and varying from -21° to -39° in 3° steps. The data for the reaction leading to the ground state of were found to be consistent with quasifree scattering of the incident protons by -state -particle clusters in . Analysis in terms of a plane-wave impulse approximation yields a momentum density distribution for the struck particles which has a half-width of 0.27 , and a probability of finding an -particle cluster in of .
