  Halo nuclei are a promising new arena for studies based on effective field
theory (EFT). We develop an EFT for shallow p-wave states and discuss the
application to elastic n-alpha scattering. In contrast to the s-wave case, both
the scattering length and effective range enter at leading order. We also
discuss the prospects of using EFT in the description of other halos, such as
the three-body halo nucleus 6He.
