Abstract
The one- or two-neutron removal reactions as well as reaction cross sections for on carbon target have been studied by using primary beam on Riken Projectile Fragment Separator in RIKEN. The longitudinal momentum distributions of fragments from and fragments from breakup have been measured at by means of direct time-of-flight method. Full width at half maximum (FWHM) of the distributions have been determined to be and for and from , and for from . The FWHM for fragments from and breakup are consistent with the Goldhaber model’s prediction. While the FWHM of fragments from is much smaller, which confirms the experimental results from MSU and GANIL, an anomalous enhancement from its neighbors has been observed in the measured reaction cross section of . The experimental data are discussed in the framework of the Glauber model. The analysis of both the fragment momentum distributions and reaction cross sections indicates a dominant -wave component in the ground state of .
