Abstract

New experimental results on in-beam gamma spectroscopy of neutron rich boron isotopes are presented for ¹⁷B and its neutron removal fragments ^14,15B, after scattering with a H₂ target. A gamma transition for ¹⁷B is observed at 1089±15 keV. The fragment ¹⁵B is observed abundantly associated with a gamma transition of 1336±10 keV. This suggests for the first time a core-excited structure for ¹⁷B thereby providing a new insight into its structure. Observations for ^12,14B are also presented. The data set provides a useful systematic study of first excited states of neutron rich boron isotopes showing the dramatic drop in excitation energy beyond N = 8.
