Description
In the normal sequence of stellar evolution,12C synthesis ordinary proceeds through the 02+ excited state at Ex = 7.65 MeV, so-called triple alpha process. At very high temperature (T9 > 1) such as supernova explosion, the 31- state at Ex = 9.64 MeV also plays an important role. But the 31- radiative decay width is still unknown and only the upper and lower limit is provided at present. For this reason, it is very important to measure the radiative width of 31- state at Ex = 9.64 MeV for better understanding of triple alpha process. In order to determine this width, we have proposed a new experiment at RCNP. In this experiment, we perform the inverse kinematics measurement of inelastic proton scattering from 12C at an incident energy of E = 20.8 MeV/u. We have already performed the test experiment. We present the results of the test experiment and the prospects of a new experiment.
