Investigation on the Halo Structure in 15C

  • The σR for 14,15C and // of 13,14C fragments from 15C, and 13C fragments from 14C breakup have been measured at 83A MeV. FWHMs of // have been determined to be 71±9MeV/c and 223±28MeV/c for 14C and 13C from 15C, and 195±21MeV/c for 13C from14C. The FWHM for 13C from 15C and 14C are consistent with Goldhaber model's prediction. While the FWHM of 14C fragments from 15C is much smaller. An anomalous enhancement from its neighbors has been observed in the measured σR of 15C. The experimental data are discussed in the framework of the Glauber model. The analysis of both // and σR data indicate a dominant s-wave component in the ground state of 15C.

Abstract: The σR for 14,15C and // of 13,14C fragments from 15C, and 13C fragments from 14C breakup have been measured at 83A MeV. FWHMs of // have been determined to be 71±9MeV/c and 223±28MeV/c for 14C and 13C from 15C, and 195±21MeV/c for 13C from14C. The FWHM for 13C from 15C and 14C are consistent with Goldhaber model's prediction. While the FWHM of 14C fragments from 15C is much smaller. An anomalous enhancement from its neighbors has been observed in the measured σR of 15C. The experimental data are discussed in the framework of the Glauber model. The analysis of both // and σR data indicate a dominant s-wave component in the ground state of 15C.
