Direct Observation of the4+-to-2+Gamma Transition inBe8

V. M. Datar; Suresh Kumar; D. R. Chakrabarty; V. Nanal; E. T. Mirgule; A. Mitra; H. H. Oza

Electromagnetic transition rates provide an important test for nuclear structure models. The nucleus 8Be exhibits a pronounced alpha-cluster structure and is a building block for more complex cluster nuclei. Here we report on the first observation of the gamma transition between the 4(+) and 2(+) states of 8Be in the 4He+4He reaction. The measured on-resonance cross section of 165+/-54 nb leads to a B(E2) of25+/-8e(2) fm(4), in good agreement with alpha-cluster models and sophisticated ab initio structure calculations.

Measurement of the energy dependence of level density over a wide range in neighbouring odd and even-even nuclei

U. K. Pal; D.R. Chakrabarty; V.M. Datar; Suresh Kumar; E. T. Mirgule; H. H. Oza

The energy dependence of the nuclear level density in 69As and 70Ge has been extracted from the first-step evaporation proton spectra in the reactions 12C+ 58Ni and 12C+ 59Co at Ebeam = 36-60 MeV. Their comparison provides information on the excitation energy dependence of the pairing and shell effect over a wide range of ~5-24 MeV.
