We systematically determine ground-state and saddle-point shapes and masses for 1305 heavy and superheavy nuclei with $Z=98$–126 and $N=134$–$192$, including odd-$A$ and odd–odd systems. From these we derive static fission barrier heights, one- and two-nucleon separation energies, and $Q_{\alpha }$ values for g.s. to g.s. transitions. Our study is performed within the microscopic–macroscopic method with the deformed Woods–Saxon single-particle potential and the Yukawa-plus-exponential macroscopic energy taken as the smooth part. We use parameters of the model that were fitted previously to masses of even–even heavy nuclei. For systems with odd numbers of protons, neutrons, or both, we use a standard BCS method with blocking. Ground-state shapes and energies are found by the minimization over seven axially-symmetric deformations. A search for saddle-points was performed by using the ”imaginary water flow” method in three consecutive stages, using five- (for nonaxial shapes) and seven-dimensional (for reflection-asymmetric shapes) deformation spaces. Calculated ground-state mass excess, nucleon separation- and $Q_{\alpha }$ energies, total, macroscopic (normalized to the macroscopic energy at the spherical shape) and shell corrections energies, and deformations are given for each nucleus in Table 1. Table 2 contains calculated properties of the saddle-point configurations and the fission barrier heights. In Tables 3-7, are given calculated ground-state, inner and outer saddle-point and superdeformed secondary minima characteristics for 75 actinide nuclei, from Ac to Cf, for which experimental estimates of fission barrier heights are known. These results are an additional test of our model.

我们系统地确定了1305个重核和超重核的基态和鞍点形及质量 $ž=98$–126和 $ñ=134$–$192$，包括奇数-$\mathrm{一种}$和奇数系统。从这些推论中，我们得出静态裂变势垒高度，一和二核子分离能以及${问}_{\alpha }$gs到gs过渡的值。我们的研究是在微观-宏观方法下进行的，以变形的Woods-Saxon单粒子势和Yukawa加指数的宏观能作为光滑部分。我们使用模型的参数，这些参数先前已拟合至偶数甚至重核的质量。对于质子，中子或两者均具有奇数个的系统，我们使用带阻塞的标准BCS方法。通过最小化七个轴向对称变形发现基态形状和能量。在五个连续的阶段中，使用“假想水流”方法，使用五个（对于非轴向形状）和七个（对于反射非对称形状）变形空间，来搜索鞍点。计算的基态质量过量，核子分离和${问}_{\alpha }$表1中给出了每个原子核的总能量，宏观能量（归一化为球形时的宏观能量）和壳校正能量以及变形。表2包含了鞍点构型和裂变势垒高度的计算属性。在表3-7中，给出了从Ac到Cf的75个act系原子核的计算基态，内鞍点和外鞍点以及超变形的次要最小特征，为此已知裂变屏障高度的实验估计。这些结果是我们模型的另一项检验。
