Abstract

The neutron-rich nucleus ¹³B was studied via the proton transfer reaction ⁴He(¹²Be, ¹³Bγ) at 50 A MeV. The known 4.83-MeV excited state was strongly populated and its spin and parity were assigned to 1 / 2⁺ by comparing the angular differential cross section data with DWBA calculations. This low-lying 1 / 2⁺ state is interpreted as a proton intruder state and indicates a deformation of the nucleus.
