We tabulate the ground-state odd-proton and odd-neutron spins and parities, proton and neutron pairing gaps, one- and two-neutron separation energies, quantities related to β-delayed one- and two-neutron emission probabilities, average energy and average number of emitted neutrons, β-decay energy release and half-life with respect to Gamow–Teller decay with a phenomenological treatment of first-forbidden decays, one- and two-proton separation energies, and α-decay energy release and half-life for 9318 nuclei ranging from 16O to 339136 and extending from the proton drip line to the neutron drip line. This paper is a new and improved version of Atomic Data And Nuclear Data Tables [66 131 (1997)]. The starting point of our present work is the new study (FRDM(2012)) of nuclear ground-state masses and deformations based on the finite-range droplet model and folded-Yukawa single-particle potential published in a previous issue of Atomic Data And Nuclear Data Tables [109–110, 1 (2016)]. The β-delayed neutron-emission probabilities and Gamow–Teller β-decay rates are obtained from a quasi-particle random-phase approximation with single-particle levels and wave functions at the calculated nuclear ground-state shapes as input quantities. A development since 1997 is we now use a Hauser–Feshbach approach to account for (n, γ) competition and treat first-forbidden decay in a phenomenological approach.

天体物理和放射性离子束应用的核特性(II)

我们将基态奇质子和奇中子自旋和奇偶性,质子和中子配对间隙,一中子和二中子分离能,与 β延迟的一中子和二中子发射概率,平均能量和平均发射中子数, β相对于伽莫夫-泰勒衰变的衰变能量释放和半衰期,用现象学方法处理了第一禁忌衰变,一个和两个质子的分离能,以及 α衰变的能量释放和9318核的半衰期,范围从16 O到339 136,从质子滴线延伸到中子滴线。本文是《原子数据和核数据表》的新版本和改进版本[ 66 131(1997)]。我们当前工作的起点是基于有限范围液滴模型和上一期Atomic Data And期刊上发表的折叠式Yukawa单粒子电势的核基态质量和形变的新研究(FRDM(2012))。核数据表[ 109-110,1(2016)]。的β延迟中子发射概率与伽莫夫-泰勒 β衰变速率是从准粒子随机相位近似获得的,其中在计算出的核基态形状处,单粒子能级和波函数作为输入量。自1997年以来的一项发展是,我们现在使用Hauser-Feshbach方法来解释(n,γ)竞争,并以现象学方法处理第一个禁忌衰变。
