The role of reduced mass as well as the classical hydtodvnanhcal mass in the WKB methocl is analysed. Within WKB, even for negative Q-value systems, the pre-existenci' probability is calculated. The calculations reveal rich structural information. The calculated results are compared with the values of preformed cluster model of Gupta and collaborators. The mass asymmelrt motion is shown here for the first time as a part of relative separation motion.Item Cluster pre-existence probability from WKH integral(2010) Rajeswari, N S; Balasubramaniam, MItem Construction of A Constant Current Source and Study on Its Performance(2008-04) Mahalakshmi, R; Rajeswari, N SItem Construction of A Lock-In Amplifier And Study on Its Internal Calibration(2008-04) Sharmila Sri, S; Rajeswari, N SItem Construction of Microcontroller Based Device to Monitor Humidity, Pressure and Temperature Using Sensors(2009-04) Nandhini, M; Rajeswari, N SItem Decay system formed in reaction(2012) Rajeswari, N SItem Development of Nano Crystalline Nickel Coating for Engineering Applications(2010-04) Menaka, R; Rajeswari, N SItem Effect of Annealing Temparature on the Structural and Optical Characteristics of Cobalt Doped Zinc Oxide(2023-05) Sahaana, B; Rajeswari, N SItem Empirical preformation probability for the decay of - Ra(2013) Rajeswari, N SItem An empirical relation for cluster decay preformation probability(2014) Rajeswari, N SEmpirical relations for the preformation probability of cluster decay process in terms of the Q-value, mass aisymmetry (?;), mass number of the emitted cluster A2 is analyzed based on the discrepancy between the calculated and experimental half-lives of the cluster emitters. For the different empirical expressions considered corresponding to different physical quantities the preformation probability for the complete binary breakup of ^^®Ra is calculated and the obtained results are compared with the preformed cluster model calculation (Pq(PCM)) and another calculation in which the overlapping penetration probability is treated as the preformation probability (Po(/r)). Our empirical results for the use of Q-value compare well with Po(/r). Results due to the use of Q and its powers along with the combination of mass number A2 of the cluster emitted, and mass asymmetry rj, reveal that preformation factor depends strongly on Q-value rather than A 2 and r/. Calculated half-lives of different cluster decays for the use of emi)iiical Po values are found to be in good agreement with the experimental values.Item Energy Audit in a Selected Spinning Mill for the Assessment of Electrical Energy Consumption and Saving(2009-04) Kavitha, N; Rajeswari, N SItem Environmental Aware RF Home Automation System(2015) Rajeswari, N SItem Exotic decay modes of odd-Z (105-119) superheavy nuclei(2014) Rajeswari, N SHalf-lives of proton emission for proton emitters with Z — 51 to 83 are calculated, in the framework of unified fission model with the penetrability calculated using the WKB appro.ximation. For all the ground and isomeric state of the proton, the deformation degree of freedom is included. Calculated half-lives are in good agreement with the experimental ones. Experimentally for a few isotopes, proton and alpha branches are reported. Hence we have calculated the half-lives of al]jiia deca> for these eleincnis. For parent nuclei ‘ '^'Ta, “T1 and * ^Tl. the alpha decay mode is preferred ovei the inoio emission. Further, the calculations are extended to find half-lives of suijerlieavy element with odd juotoii number in the range Z = 105 to 119, for both proton, alpha and for a few cluster decays. ( 'alciilal ions on superheavy elements reveal that cluster radioactivity has half-lives comparable with proton emissions. It is found that proton emission is the prirnai’y competing decay mode with respect to alpha decay foi' superheavy elements. Among considered clusters, ^^C, and ^“'Mg are found to have lowest half-liv(;s among other N = Z clusters and for a. few clusters the half-lives are found to be coni]3fUfible with that of proton emission.Item Fragmentation Potential for the Ternary Decay OF 252CF(2013-05) Deepa, G; Rajeswari, N S
