|Title:||A Measurement of T₂₀ for the ¹H(đ,ϒ)³He Reaction and D-State Effects in ³He|
|Authors:||Vetterli, Christian Michel|
|Abstract:||<p>The tensor analysing power T₂₀ for the radiative capture reaction ¹H(đ,ϒ)³He has been measured in order to test new three-body wave functions. This observable arises from the D-state of ³He. An effective two-body direct radiative capture calculation, which was previously shown to fit the a₂ coefficient of a Legendre polynomial expansion of the differential cross-section, is found to give a good description of the present data. A range of 5% to 9% is deduced for the D-state probability in the ³He ground state wave function. A value of -0.032 ± 0.014 for the asymptotic D/S state ratio is extracted from the data although it is found to be model dependent.</p>|
