Search for the radiative capture reaction d+d → 4He+γ from the ddμ muonic molecule state

“…proceeding from the J = 1 state of ddµ molecules [6], [7] gave the value R p (n/p) = 1.42 ±0.03. It agreed with the ratio from [5] determined from the elaborate (and model dependent) analysis of the in-flight data. Rates of ddµ fusion reactions (2),(3) from the p-wave were experimentally measured [8] and corresponding nuclear reaction constants were extracted from MC data [9].…”

“…Exposures made with H/D mixture allowed detection of reaction (5), which was used both for energy calibrating and checking the γ-quanta detection efficiency.…”

“…Study of the MC fusion process in ddµ muonic molecule resulted in the complimentary and detailed information about charge-symmetric reactions d(d, n) 3 He and d(d, p) 3 H. A significant difference in the p-wave parts of the d(d, p) 3 H and d(d, n) 3 He reaction yields was observed in the experiments with low energy polarized deuteron beams [5]. Comparison of two reaction branches showed some s-wave enhancement together with essential p-wave suppression of the proton branch.…”
