The isobaric analog states with isospin T = 1 in triplet of the A = 14 nuclei: ¹⁴C, ¹⁴N, and ¹⁴O, are studied. Signs of neutron halo in the 1⁻ (6.09 MeV) state of ¹⁴C have been revealed earlier by two groups. We confirm this result and study isobaric analog 1⁻ states of neighboring ¹⁴N and ¹⁴O nuclei. The differential cross sections of the ¹⁴C(α, α)¹⁴C* (6.09 MeV, 1⁻) inelastic scattering, the ¹³C(³He, d)¹⁴N* (8.06 MeV, 1⁻), and the ¹⁴N(³He, t)¹⁴O* (5.17 MeV, 1⁻) reactions are analyzed by two methods: the modified diffraction method and the method of asymptotic normalization coefficients. The rms radii for all three mirror nuclei in the studied 1⁻ states are found almost the same: 2.7 ± 0.1 fm for ¹⁴C, 2.67± 0.07 fm for ¹⁴N, and 2.6 ± 0.2 fm for ¹⁴O. The signs of proton halo in the 1⁻ state of ¹⁴N are identified for the first time.

与同位旋等压模拟状态Ť在的三重= 1甲= 14个核：¹⁴ C，¹⁴ N，和¹⁴ O，进行了研究。在1中子晕的迹象^-的（6.09兆电子伏）的状态¹⁴ Ç已经由两组早些时候透露。我们确认这一结果，研究等压模拟1 ^-邻近的国家¹⁴ N和^14个Ø核。所述的微分截面¹⁴ C（α，α）¹⁴ C *（6.09兆电子伏，1 ^- ）非弹性散射，所述¹³ C（³赫，d）¹⁴ N *（8.06 MeV的，1^- ），和¹⁴ N（³赫，T）¹⁴的O *（5.17兆电子伏，1 ^-改性衍射法和渐近归一化系数的方法：）反应通过两种方法进行分析。的均方根为在所研究的1个所有三个镜像核半径^-状态被发现几乎是相同的：2.7 ±0.1的FM为¹⁴ C，2.67±0.07 FM为¹⁴ N，和2.6±0.2的FM为¹⁴ O.质子晕的迹象在1 ^-的状态¹⁴ N被确定为第一次。
