Experimental data on ground- and excited-state properties for all known nuclei with mass number A=69 have been compiled and evaluated. States populated in radioactive decay, as well as in nuclear reactions, have been considered. For these nuclei, level and decay schemes, as well as tables of nuclear properties, are given in detail. This work supersedes the 2013 evaluation by C.D. Nesaraja (2014Ne01).

Evaluated spectroscopic data and level schemes are presented for 25N (unobserved), 25O, 25F, 25Ne, 25Na, 25Mg, 25Al, 25Si, and 25P based on the measured decay and nuclear reaction studies. This evaluation for A=25 supersedes the earlier one by R.B. Firestone (2009Fi05). Overall the decay datasets associated with 25Ne, 25Na, and 25Mg remain the same compared with those in the previous evaluation, 2009Fi05, however, new β-n decay datasets are added in 25Ne along with new reaction datasets almost for all of the above mentioned nuclides from older and new references.
Other highlights of this evaluation are the following:
Ground state of 25O is neutron unbound. Several new articles reported resonance energies of this nuclide, studied using radioactive beams, like 24O,27Ne, 26F, etc. These results have been included in this evaluation.
Due to the lack of direct experimental evidence, a tentative (5/2+) assignment for the ground state and no spin-parity assignments for the known excited states of 25Si has been adopted in the present evaluation.
In the absence of experimental evidence, tentative (1/2+) assignment has been adopted for the ground state of 25P. As suggested in 2015Fe02, light-ion scattering experiment in the inverse kinematics seems to be a probable probe for investigating the low-lying states of 25P, which are the mirror analogs of the states of 25Ne.

Available information pertaining to the nuclear structure of ground and excited states for all known nuclei with mass numbers A=248 has been compiled and evaluated. The adopted level and decay schemes, as well as the detailed nuclear properties and configuration assignments based on experimental data, are presented for these nuclides. When there are insufficient data, expected values from systematics of nuclear properties and/or theoretical calculations are utilized. Unexpected or discrepant experimental results are also noted. This work supersedes the 2014 evaluation by M.J. Martin (2014Ma86).
关于所有已知质量数为A=248的原子核的基态和激发态核结构的现有信息已被汇编和评估。给出了这些核素所采用的能级和衰变方案，以及基于实验数据的详细核性质和组态分配。当数据不足时，利用核性质系统学和（或）理论计算的期望值。意外的或不一致的实验结果也被注意到。这项工作取代了2014年M.J. Martin （2014Ma86）的评估。
