用与CLARAarray耦合的PRISMA磁谱仪研究了40,41,42ar同位素中选定跃迁的射线角分布。这些跃迁分布在40ar +208Pb反应中通过中子转移获得的Ar同位素中。通过与已知E2跃迁的实验角分布形状的比较，我们更牢固地建立了激发态的自旋和宇称。特别地，用声子-费米子耦合态讨论了通过跃迁的态。与预期的完全对准自旋的比较表明，已经达到了很高的自旋对准水平。
Angular distributions of-rays for selected transitions in40, 41, 42Ar isotopes have been studied with the PRISMA magnetic spectrometer coupled to the CLARAarray. These transitions were populated in Ar isotopes reached via neutron transfer in the40Ar +208Pb reaction. By comparison with the shape of the experimental angular distribution of the known E2 transitions we established more firmly the spin and parity of excited states. In particular, in41Ar for thestate through thetransition whose structure was discussed in terms of a phonon-fermion coupled state. The comparison with the expected fully aligned spin indicated that a high level of spin alignment has been reached.
