Abstract

The charge-changing cross-section (

σ_{c c}

) of the dripline nucleus, ¹⁹B, was measured using the transmission technique at RIBF, RIKEN, to understand its root mean square proton radius (

R_{p}

). This new measurement will be the first determination of the

R_{p}

for the Borromean nucleus, ¹⁹B. The new value of

R_{p}

will help determine the geometrical structure of ¹⁹B and the neutron-neutron correlation in the Borromean nucleus.

波罗的海晕核 19B 的质子半径研究

理化学研究所的 RIBF 使用透射技术测量了滴线核 19B 的电荷变化截面（σcc），以了解其质子半径（Rp）的均方根。这次新的测量将是首次测定波罗的海核 19B 的 Rp。新的 Rp 值将有助于确定 19B 的几何结构和波罗曼核中的中子-中子相关性。
