摘要:

在$E$($^3$ He)=40 MeV下测量了导致$^{12}$ N的1 $^+$(基态)、2 $^+$(0.96 MeV)、2 $^{-}$(1.19 MeV)和1 $^{-}$(1.80 MeV)态形成的$^{12}$ C($^3$ He,t)$^{12}$ N反应的微分截面。在修正的衍射模型(MDM)和扭曲波玻恩近似(DWBA)的数据进行分析。增强的$rms$半径获得了基态,2 $^{-}$(1.19 MeV),和1 $^{-}$(1.80 MeV)的状态。我们发现,$^{12}$ B,$^{12}$ N,和$^{12}$ C在IAS与T=1,自旋宇称2 $^{-}$和1 $^{-}$有增加的半径和中子和质子晕态的性质。

英文摘要:

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.
