Gamma-rays from an incomplete fusion reaction induced by 95 MeV 14N

Investigation of the influence of incomplete fusion on complete fusion of16O induced reactions at moderate excitation energies

“…The studies of coincidence relationships between the outgoing α-particles and the discrete γ-rays of the heavy residues unambiguously has also proved that in these reactions a massive part of the projectile fuses with the target while that remaining escapes at forward angles carrying a large part of the kinetic energy and angular momentum [8]. Furthermore, a few reports [9][10][11] have shown that the population of low-spin states are observed to be hindered and/or less fed in the case of ICF. This reveals the occurrence of ICF due to the influence of centrifugal potential in the peripheral interactions, where driving angular momentum limits do not allow CF.…”

“…These reactions were first observed by Britt and Quinton [16] with the experimental evidence of forward peaked α-particles in the interaction of heavy projectile target systems at energies ≈10.5 MeV/A. Particle-gamma coincidence studies by Inamura et al [9] contributed strongly to the understanding of the mechanism of ICF reactions. Furthermore such reactions are difficult to explain in terms of deep inelastic collisions as the mass flow is always from projectile to target.…”

Neutron transfer in the C13+Au197 reaction from gold isotope residuals

“…This has traditionally involved using weakly-bound nuclei such as 7 Li or 9 Be, where, respectively, a triton or 5 He nucleus is transferred to the target nucleus, ejecting an α particle, or vice versa. These massive-transfer reactions were studied using stronglybound projectiles such as 12 C, 14 N, and 16 O [10][11][12][13][14]. These type of reactions are also successfully used now with radioactive ion beams [15].…”

Investigation of complete and incomplete fusion in20Ne +51V system using recoil range measurement

“…Ever since the observation of the first ICF reaction by Britt and Quinton [9], numerous studies have been carried out to explore the mechanism involve in the ICF reactions. However, a real breakthrough was achieved by Inamura et al [10] by performing the particle-γ coincidence measurements and claiming that ICF reactions were arising due to the break-up of incident projectile in peripheral collisions. It was suggested by Morgenstern et al [11] and later on confirmed by several authors [5,6,12] that probability of ICF reaction increases with the increase in incident beam energy.…”
