Query: 3H and 3He calculations without angular momentum decomposition   Results for the three nucleon (3N) bound state carried out using the "three
dimensional" (3D) formalism are presented. In this approach calculations are
performed without the use of angular momentum decomposition and instead rely
directly on the 3D degrees of freedom of the nucleons. In this paper, for the
first time, 3D results for $^{3}$He bound state with the inclusion of the
screened Coulomb potential are compared to $^{3}$H calculations. Additionally,
using these results, matrix elements of simple current operators related to the
description of beta decay of the triton are given. All computations are carried
out using the first generation of NNLO two nucleon (2N) and 3N forces from the
Bochum - Bonn group.
