Abstract

The triple alpha reaction is one of the most important reactions in the nuclear astrophysics. However, its reaction rate in high temperature environments at T₉>2 was still uncertain. One of the major origins of the uncertainty was that the radiative-decay probability of the 3⁻₁ state in ¹²C was unknown. In the present work, we have determined the radiative-decay probability of the 3⁻₁ state to be 1.3[+1.2][-1.1] × 10⁻⁶ by measuring the ¹H(¹²C, ¹²Cp) reaction for the first time, and derived the triple alpha reaction rate in high temperature environments from the measured radiative-decay probability. The present result suggests that the 3⁻₁ state noticeably enhances the triple alpha reaction rate although the contribution from the 3⁻₁ state had been assumed to be small.

Abstract

The photo-production of ϕ mesons from Li, C, Al, and Cu at forward angles has been measured at Eγ=1.5–2.4GeV. The number of events for incoherent ϕ photo-production is found to have a target mass number dependence of A0.72±0.07 in the kinematical region of |t|⩽0.6GeV2/c2. The total cross section of the ϕ–nucleon interaction, σϕN, has been estimated as 35−11+17mb using the A-dependence of the ϕ photo-production yield and a Glauber-type multiple scattering theory. This value is much larger than σϕN in free space, suggesting that the ϕ properties might change in the nuclear medium.

Abstract

Abstract: The excitation and subsequent proton decay of the isoscalar giant dipole resonance (ISGDR) in 208Pb have been investigated via the reaction at 400 MeV. Excitation of the ISGDR has been identified by the difference-of-spectra method. The enhancement of the ISGDR strength at high excitation energies observed in the multipole-decomposition-analysis of the singles spectra is not present in the excitation energy spectrum obtained in coincidence measurement. The partial branching ratios for direct proton decay of ISGDR to low-lying states of 207Tl have been determined and the results are compared with predictions of continuum random-phase-approximation (CRPA) calculations.

Abstract

Abstract: The strength distribution of the isoscalar giant dipole resonance (ISGDR) in 58Ni has been obtained over the energy range 10.5–49.5 MeV via extreme forward angle scattering (including 0°) of 386 MeV α particles. We observe a “bi-modal” E1 strength distribution for the first time in an nucleus. The observed ISGDR strength distribution is in reasonable agreement with the predictions of a recent RPA calculation. [Copyright &y& Elsevier]

Abstract

The isoscalar giant dipole resonance (ISGDR) in 208Pb has been investigated with inelastic α-scattering of 400 MeV at extremely forward angles, including 0°. Energy spectra, virtually free from instrumental background, have been obtained and the ISGDR strength distribution has been extracted using a multipole-decomposition analysis (MDA). A difference-of-spectra approach yields the same ISGDR centroid energy as with MDA. These results lead to a value for nuclear incompressibility that is consistent for both the isoscalar dipole and monopole modes. [Copyright &y& Elsevier]

Abstract

Charged particle decay of the s-hole state in 11B was measured in coincidence with the quasifree 12C(p,2p) reaction at 392 MeV incident energy. Triton-decay was found to be dominant despite its smaller Q-value than that of α-decay. The measured decay pattern is compared to the results of statistical model and microscopic SU(3)-cluster model calculations. The energy spectrum around the s-hole state exhibits three bump-like structures, which can be qualitatively explained by a recent shell-model calculation. [Copyright &y& Elsevier]
