[en] The T=0 states of 4He are investigated in complete Nhw shell-model spaces with 3<=N<=10 using a realistic two-body interaction based on the Sussex matrix elements. It is found that it is possible to describe the ground-state properties and the T=0 excited spectrum of this nucleus in a consistent manner provided the model space is enlarged up to 10hw of oscillator excitation. In particular, the lowest 1- state appears in our 10hw spectrum with an excitation energy comparable to the energy of 24.1 MeV favored by recent experimental investigations of the reaction 2(d,p)3H. Moreover, the D-state admixture of the large-basis ground-state wave function amounts to 4.7%, in fair agreement with the value deduced from recent analyzing power measurements of the reaction 2(d,gamma)4He.
