Deuteron NN*(1440) components from a chiral quark model

We present a nonrelativistic coupled-channel calculation of the deuteron structure including Delta Delta and NN^(1440) channels, besides the standard NN S and D-wave components. All the necessary building blocks to perform the calculation have been obtained from the same underlying quark model. The calculated NN^(1440) probabilities find support in the explanation given to different deuteron reactions.
