  • A cryogenic front-end preamplifier operating at 120 K for bolometric detector 
    Reza, A.; Vatsa, V.; Pose, M.S.; Mazumdar, A.; Garai, A.; Krishnamoorthy, H.; Gupta, G.; Nanal, V.; Pillay, R.G.; Shrivastava, A. (2020-03-16)
    In this paper, the design and test results of a front-end cryogenic amplifier for a bolometer detector are presented. The amplifier is implemented with two low-noise Si JFETs, where the first FET is configured as a source ...

    To probe the role of the intrinsic structure of the projectile on subbarrier fusion, measurement of fusion cross sections has been carried out in a 9 Be + 197Au system in the energy range Ec.m./VB ≈ 0.82 to 1.16 ...
  • Investigating neutron transfer in the Be 9 + Au 197 system 
    Kaushik, M.; Pandit, S. K.; Parkar, V. V.; Gupta, G.; Thakur, S.; Nanal, V.; Krishnamoorthy, H.; Shrivastava, A.; Palshetkar, C. S.; Mahata, K.; Ramachandran, K.; Pal, S.; Pillay, R. G.; Singh, P. P. (2021-10-18)
    In this work n-transfer and incomplete fusion cross sections for the 9 Be + 197Au system are reported over a wide energy range, Ec.m. ≈ 29-45 MeV. The experiment was carried out using the activation technique and off-line ...
  • Neutron transfer in 9Be + 159Tb system 
    Kaushik, M.; Gupta, G.; Parkar, V.V.; Pandit, S.K.; Thakur, S.; Nanal, V.; Shrivastava, A.; Pillay, R.G.; Krishnamoorthy, H.; Mahata, K.; Pal, S.; Palshetkar, C.S.; Ramachandran, K.; Singh, P.P. (2022-08-18)
    One neutron stripping cross sections (σ-1n) are measured in 9Be+159Tb system in the energy range Ecm/VB∼ 0.79–1.24 using offline gamma counting technique. The CRC model calculations including the ground state and the 2+ ...
  • New limit for the half-life of double beta decay of 94Zr to the first excited state of 94Mo
