Elastic scattering of several hydrogen and helium isotopes from tritium

Radiativeα-capture cross sections from realistic nucleon-nucleon interactions and variational Monte Carlo wave functions

“…• , with the knowledge that there must be at least one node in the wave function) throughout the region below 8 MeV for both α-t and α-3 He systems [40][41][42][43]. This lack of features is particularly unfortunate in that by far the most important reaction mechanisms for radiative capture in this system are E1 captures from S-and D-wave scattering states.…”

Improved evaluation of the differential cross sections of the3H(d,n)4He reaction for deuteron energies between 3 and 7 MeV

“…The full curve is the present result, the dasheddotted curve is the previous solution, and the dashed curve is from [2]. The data points are from [4] Like the other charged-particle data of the 3H(d,n)~He reaction, these data also have a lower scale than the recommended scale of the previous evaluation [33. However, the difference is not important.…”

“…The three excitation functions included here were measured by the associated-particle method via the reaction 3H(d,a)n for the c~-particle angles of 18.0, 27.3 and 37.0 ~ [4]. An angular uncertainty of 0.1 ~ a scale error of 3 %, and a typical differential error of 4 % are given for these data.…”

“…This evaluation relied strongly on previous experimental data between 7 and 16.5 MeV [3]. The three excitation functions [4] included here cover deuteron energies from 4 to 11 MeV. They were not used by Liskien and Paulsen [-2] or in the previous evaluation [3].…”

Benchmark calculation ofp−H3andn−He3

“…In particular, below the d − d threshold there exist (since many years) several measurements of the p-3 H elastic differential cross section [35][36][37][38][39][40][41], n-3 He elastic differential cross section [42,43] and total cross section [42][43][44][45], and n-3 He elastic analyzing powers [46][47][48][49][50]. Regarding the n-3 He → p-3 H charge exchange reaction, there exist mainly measurements of the total cross section [43,45,[51][52][53][54][55][56][57].…”
