In our last paper, we started with the 87Sr atomic transition frequency which is 429228004229872.99(8) Hz, calculated out and predicted the 229Th nuclear transition frequency which is 2020407384335167.11(38) Hz, and calculated out more precise value of the atomic unit of time tau which is 2.41888432658653284(45)×10-17 s, and with the later calculated out the atomic transition frequencies of 27Al+、199Hg、115In+ and 199Hg+. In this paper, we employ this same method to calculate out and predict the hydrogen atomic 1S—2S transition frequency, which is 2466061413187017.96(46) Hz.

Actinium-225 (Ac-225) is a synthetic isotope of actinium with significant applications innuclear medicine, particularly in targeted alpha therapy (TAT) for cancer treatment. Ac-225,with a half-life of 10 days, undergoes a decay sequence that emits highly energetic alphaparticles, making it effective for selectively destroying cancer cells while minimizing damageto surrounding healthy tissue. This paper examines the nature, production, and decay pathwaysof Ac-225, including its role in the 4n+1 neptunium decay series and artificial productionthrough high-energy proton spallation of thorium-232. Furthermore, it explores Ac-225’sbinding energy, decay characteristics, and the advantages of its daughter isotope, bismuth-213,in therapeutic applications. The use of radionuclide generators for Ac-225 production and itsintegration into radiopharmaceuticals is also discussed. Given its cytotoxic potential andability to selectively target tumors, Ac-225 represents a major breakthrough in nuclearmedicine, providing an effective alternative to traditional cancer treatments.

Current nuclear fusion research faces immense engineering and economic challenges, primarily relying on complex plasma confinement methods such as tokamaks and laser-induced inertial confinement. These approaches demand extreme conditions and significant infrastructure investments, delaying commercialization. This paper proposes an alternative fusion method utilizing sonofusion (bubble fusion), where microbubbles collapse under ultrasonic and microwave stimulation to generate localized extreme conditions.A novel approach is introduced by employing liquid hydrogen confined within a high-pressure capsule, accompanied by a lithium catalyst. The system is designed to leverage cavitation-induced fusion through external ultrasonic, microwave, and magnetic field stimuli. The energy produced is transferred to an external water tank, where conventional steam turbine cycles can harvest it. This proposed method is estimated to cost only 1/100th of existing fusion facilities, offering a more accessible and scalable experimental pathway to fusion energy.Accompanying this research are various schematics and diagrams that provide a detailed visualization of the proposed system architecture, reaction chamber, and energy recovery mechanisms. These visual aids ensure clarity in the theoretical underpinnings and technical feasibility of the approach.
