The present evaluation of the known A=233 nuclides (²³³Fr, ²³³Ra, ²³³Ac, ²³³Th, ²³³Pa, ²³³U, ²³³Np, ²³³Pu, ²³³Am, ²³³Cm) and ²³³Bk represents an update and revision, after 15 years of the previous evaluation of A=233 published by B. Singh and J.K. Tuli (2005Si15). Laboratory identification of ²³³Bk nuclide is still considered as tentative. Various decay and reaction data are evaluated and compared. Adopted data, levels, gammas, level half-lives, spins, parities, and configuration assignments are provided. For ²³³Fr, ²³³Ra, ²³³Ac, ²³³Pu, ²³³Am and ²³³Cm, information is available for the respective ground states only. The decay schemes from β⁻ decays of ²³³Fr and ²³³Ra, and from ε decay of ²³³Am and ²³³Cm are unknown, while those from β⁻ decay of ²³³Ac, and from ε decay of ²³³Np are considered incomplete. The α decay of ²³⁷Np to ²³³Pa has been studied in detail by many investigators, yet the decay scheme is considered incomplete as several very low-energy transitions are involved, without the knowledge of their intensities, resulting in mismatch of directly measured α feedings and those deduced from γ-transition intensity balances. The decay schemes from α decays of ²³⁷Am, ²³⁷Cm and ²³⁷Cf to respective A=233 daughters are considered incomplete. Particle-transfer and high-spin data are available for ²³³Th, ²³³Pa and ²³³U nuclei, which remain the most extensively studied in this mass chain. However, data for half-lives for the excited states are available only for one level in ²³³Pa, and for five levels in ²³³U, thus limiting the knowledge of reduced transition probabilities in this mass chain.

目前对已知A = 233核素（²³³ Fr，²³³ Ra，²³³ Ac，²³³ Th，²³³ Pa，²³³ U，²³³ Np，²³³ Pu，²³³ Am，²³³ Cm）和²³³ Bk的评估代表了更新和修订，是B. Singh和JK Tuli（2005Si15）发布的对A = 233的先前评估15年后得出的结果。²³³ Bk核素的实验室鉴定仍被认为是试验性的。评估并比较了各种衰减和反应数据。提供了采用的数据，级别，伽马，级别半衰期，自旋，奇偶校验和配置分配。为²³³Fr，²³³ Ra，²³³ Ac，²³³ Pu，²³³ Am和²³³ Cm，信息仅适用于相应的基态。从衰减方案β ^-的衰变²³³ Fr与²³³ RA和从ε的衰变²³³ AM到²³³厘米是未知的，而来自β ^-的衰变²³³交流，并从ε的衰变²³³ Np个被不完全考虑。的α衰变²³⁷ Np个到²³³许多研究人员已经对Pa进行了详细的研究，但是由于涉及多个非常低能量的跃迁，因此衰减方案被认为是不完整的，在不了解跃迁强度的情况下，导致直接测量的α进料与从γ跃迁强度推论得出的失配余额。从²³⁷ Am，²³⁷ Cm和²³⁷ Cf的α衰变到各自的A = 233子代的衰变方案被认为是不完整的。²³³ Th，²³³ Pa和^233的颗粒传输和高自旋数据可用U核，在此质量链中仍然是研究最广泛的。但是，激发态的半衰期数据仅在²³³ Pa中一个级别可用，而在²³³ U中仅五个级别可用，因此限制了该质量链中跃迁概率降低的知识。
