摘要

A new measurement of the ²H(¹⁵C,³He)¹⁴B reaction was conducted to investigate proton shell evolution in neutron-rich carbon and boron isotopes. The experiment employed a radioactive beam of ¹⁵C with a higher energy at 28.3 MeV/u and a large acceptance charged particle detector array LACPU, enabling coincident measurement of high-lying unbound states in ¹⁴B that include π 0 p _1/2- π 0 p _3/2 transitions. A newly observed 3.45(35)-MeV resonance with a statistical significance of 3.1 σ in ¹⁴B exhibits π 0 p _1/2- rather than π 0 p _3/2-dominant character according to structural model predictions. The extracted proton spectroscopic factor of 0.16 ± 0.06 for ¹⁵C_g.s. not only follows the systematic decreasing trend in neutron-rich carbon isotopes but also agrees with theoretical predictions, providing clear evidence for the Z = 6 magicity in ¹⁵C. Furthermore, systematic analysis of the energy splitting between the π 0 p _3/2 and π 0 p _1/2 orbitals in ¹²⁻¹⁴B reinforces the robustness of this magic number in neutron-rich nuclei systems.
