<jats:title>Abstract</jats:title>
<jats:p>We report on X-ray studies of the gamma-ray pulsar PSR J1418−6058 in the Rabbit pulsar wind nebula (PWN) carried out using archival <jats:italic>Chandra</jats:italic> and <jats:italic>XMM-Newton</jats:italic> observations. A refined timing analysis performed with the 120 ks <jats:italic>XMM-Newton</jats:italic> data finds significant (<jats:italic>p</jats:italic> ≈ 10<jats:sup>−7</jats:sup>) pulsation at <jats:italic>P</jats:italic> ≈ 110 ms which is consistent with that measured with the <jats:italic>Fermi</jats:italic> Large Area Telescope (LAT). In the <jats:italic>Chandra</jats:italic> image, we find extended emission around the pulsar similar to those seen around other pulsars in young PWNe, which further argues association between PSR J1418−6058 and the Rabbit PWN. The X-ray spectrum of the pulsar is hard and similar to those of soft-gamma pulsars. Hence PSR J1418−6058 may add to the list of soft-gamma pulsars.</jats:p>
