摘要
The first two excited states of 19Ne have been populated by the reaction 19F(p, n), and the de-excitation γ-rays have been detected. The half-lives T 1 2 have been remeasured. The gamma yield has been observed in a proton energy range from 4.4 MeV to 6.1 MeV. The g-factor of the 5 2+ level has been determined by the pulsed-beam DDCA method. The results are T 1 2 = 17.7±0.7 ns, g = -0.296±0.003 for the 5 2+ 238 keV state and T 1 2 < 0.3 ns for the 1 2- 275 keV state. The g-factor is compared with values predicted by various models. The mirror theorem of Sachs is applied. © 1969.
