We have studied here the contribution of Indian Scientists associated with Prof. Raj K. Gupta to cold nuclear phenomena during the last almost four decades, which led to the discovery of fourth kind of natural radioactivity (also known as Cluster Radioactivity, CR) and to the extension of periodic table to super heavy nuclei. It is exclusively pointed out how the Quantum Mechanical Fragmentation Theory (QMFT) advanced by Prof. Raj K. Gupta and Collaborators led to the discovery of unique phenomenon of CR along with the predictions leading to the synthesis of super heavy elements. We have also mentioned the development of dynamical theories based on QMFT, the Preformed Cluster Model(PCM) and the dynamical cluster-decay model (DCM), to study the ground and excited state decays of nuclei, respectively, by Gupta and Collaborators. It is matter of great honor and pride for us to bring out this study to enthuse the young researchers to come up with novel ideas and have inspiration from the scientific contributions of Prof. Raj K. Gupta who is coincidentally celebrating his platinum jubilee birthday anniversary this year.

Gupta教授和合作者提出的量子力学碎片理论（QMFT）是如何导致CR独特现象的发现以及导致超重元素合成的预测的。我们还提到了基于QMFT的动力学理论，预制簇模型（PCM）和动力学簇衰变模型（DCM）的发展，分别研究了古普塔（Gupta）和协作者（Collaborator）的原子核基态和激发态衰变。开展这项研究，以激励年轻的研究人员提出新颖的想法，并从Raj K. Gupta教授的科学贡献中汲取灵感，他正巧地庆祝自己的白金禧诞辰周年，这是我们感到非常荣幸和自豪。年。
