论文摘要
$^{12} $ c（$^3 $ he，t）$^{12} $ n反应的差分横截面，导致形成1 $^+$（地面状态），2 $^+$（0.96 meV），2 $^{ - } { - } $（1.19 mev），以及1 $^{$^nest $^{ - $^{ - 1.80 mev） $ e $（$^3 $ he）= 40 meV。数据的分析是在修改的衍射模型（MDM）和扭曲的波出生近似（DWBA）中进行的。获得地面的增强$ RMS $ RADII，2 $^{ - } $（1.19 MEV）和1 $^{ - } $（1.80 MEV）状态。我们透露，$^{12} $ b，$^{12} $ n，$^{12} $ c在t = 1的IAS中，旋转 - 差异2 $^{ - } $和1 $^{ - } $具有增加的半径和neuton和Proton halo ano的属性。
The differential cross sections of the $^{12}$C($^3$He,t)$^{12}$N reaction leading to formation of the 1$^+$ (ground state), 2$^+$(0.96 MeV), 2$^{-}$(1.19 MeV), and 1$^{-}$(1.80 MeV) states of $^{12}$N are measured at $E$($^3$He)=40 MeV. The analysis of the data is carried out within the modified diffraction model (MDM) and distorted wave Born approximation (DWBA). Enhanced $rms$ radii were obtained for the ground, 2$^{-}$(1.19 MeV), and 1$^{-}$(1.80 MeV) states. We revealed that $^{12}$B, $^{12}$N, and $^{12}$C in the IAS with T=1, and spin-parities 2$^{-}$ and 1$^{-}$ have increased radii and exhibit properties of neutron and proton halo states.
