Journal ArticleDOI
Different supramolecular hydrogen bond structures and significant changes in magnetic properties in dinuclear μ2-1,1-N3 copper(II) complexes with very similar tridentate Schiff base blocking ligands
Mau Sinha Ray,Ashutosh Ghosh,Rupayan Bhattacharya,Gurucharan Mukhopadhyay,Michael G. B. Drew,Joan Ribas +5 more
TL;DR: Variable-temperature magnetic susceptibility measurements and magnetization measurements at 2 K reveal that complexes and have antiferromagnetic coupling while has ferrom electromagnetic coupling which is also confirmed by EPR spectra at 4-300 K.
Journal ArticleDOI
Dynamical calculations of the above-barrier heavy-ion fusion cross sections using Hartree-Fock nuclear densities with the SKX coefficient set
Journal ArticleDOI
Elastic scattering and fusion cross sections for 7 Be, 7 Li + 27 Al systems
K. Kalita,S. Verma,Reeshu Singh,Jiten Das,Akhil Jhingan,N. Madhavan,S. Nath,T. Varughese,P. Sugathan,V. V. Parkar,K. Mahata,K. Ramachandran,A. K. Shrivastava,A. Chatterjee,S. Kailas,S. Barua,P. K. Basu,H. Majumdar,Mandira Sinha,Rupayan Bhattacharya,A. K. Sinha +20 more
TL;DR: In this paper, an optical model (OM) analysis of the quasi-elastic scattering data was carried out, and the fusion cross sections were derived at these energies by subtraction of the integrated transfer cross sections from the reaction cross sections obtained from the fits to quasielastic-scattering data.
Journal ArticleDOI
Quantitative analysis of precise heavy-ion fusion data at above-barrier energies using Skyrme-Hartree-Fock nuclear densities
TL;DR: In this article, a double-folding approach with the density-dependent M3Y NN forces including the finite-range exchange part is applied to calculate the capture (fusion) cross sections for nine reactions involving spherical nuclei.
Journal ArticleDOI
Sub- and above-barrier fusion of loosely bound 6Li with 28Si
Mandira Sinha,Mandira Sinha,H. Majumdar,P. K. Basu,Subinit Roy,Rupayan Bhattacharya,M. Biswas,M. K. Pradhan,R. Palit,I. Mazumdar,S. Kailas +10 more
TL;DR: In this paper, the authors measured the fusion cross-section of the system 6Li + 28Si using the characteristic $ \gamma$ -ray method, encompassing both the sub-barrier and abovebarrier regions, viz, E = 7-24 MeV.
