质子、α、团簇衰变和自发裂变的统一描述half- life

Unified description of the proton, alpha, cluster decays and spontaneously fissions half- life

Strachimir Cht. Mavrodiev, M. A. Deliyergiyev

摘要:

不久前,人们证明了经典(不含伽莫夫隧穿)描述放射性核衰变的普适性的可能性。这种可能性是基于Bohmian-Chetaev力学中Bohmian Psi场实在性的经典解释和Langevin-Kramers扩散机制中存在由带电粒子自旋的Gryzinski平移进动产生的耗散力的假设。本文提出了一个质子、α衰变、团簇放射性和自发裂变半衰期的统一模型,它是由总衰变能和总动能、子产物质子数和中子数、母核质子数和中子数以及一组未知的数字参数所决定的显函数。从NuDat数据库中获得的573个核的半衰期与Oganessian最近的实验数据一起,为在反问题框架下借助Alexandrov动态自正则化方法(FORTRAN程序REGN-Dubna)发现Langevin型方程的Kramers解的显式形式提供了基础。程序REGN中的程序LCH试图将未知数字参数的数目从137减少到79。该模型描述了424个年幂尺度偏差为一阶的衰变量。

英文摘要:

Some time ago the possibility of classical (without Gamow tunneling) universal description of radioactive nuclei decay was demonstrated. Such possibility is basis on the classical interpretation of Bohmian Psi-field reality in Bohmian-Chetaev mechanics and the hypothesis for the presence of dissipative forces, generated from the Gryzinski translational precession of the charged particles spin, in Langevin- Kramers diffusion mechanism. In this paper is present an unified model of proton, alpha decay, cluster radioactivity and spontaneous fission half-life as explicit function which depends on the total decay energy and kinetic energy, the number of protons and neutrons of daughter product, the number of protons and neutrons of mother nuclei and from a set) unknown digital parameters. The Half- lifes of the 573 nuclei taken from NuDat database together with the recent experimental data from Oganessian provide a basis for discovering the explicit form of the Kramers solution of Langevin type equation in a framework of inverse problem with the help of the Alexandrov dynamic auto-regularization method (FORTRAN program REGN-Dubna). The procedure LCH in program REGN permitts to reduce the number of unknown digital parameters from 137 to 79. The model describes 424 decays quantities with deviation of order one in years power scale.
