Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

The fusion of neutron-rich carbon, oxygen or neon isotopes plays an important role for the explanation of the so-called X-ray superbursts which occur in the carbon-enriched outer layers of accreting neutron stars. While measurements of many of the critical fusion reactions (e.g., 24C + 24C) are outside today’s experimental capabilities, some systems closer to the valley of stability can already be measured using existing technologies. In this contribution I will report on measurements of the fusion cross sections of 10,12,13,14,15C on 12C with an active target-detector system consisting of a methane-filled MUlti-Sampling Ionization Chamber (MUSIC) and stable and radioactive beams obtained from the Argonne In-flight facility. The principle of this detector will be described and experimental results and future plans for similar studies with MUSIC will be discussed.
