2004 CAP MEDAL WINNERS:

	The CAP-INO Medal for Outstanding Achievement in Applied Photonics is awarded to: Nicolas Jaeger, University of British Columbia, for his contribution in the field of sensors and sensor systems for power utility applications as well as in the area of ultrahigh-speed integrated-optic modulators.
	The CAP-CRM Prize in Theoretical and Mathematical Physics is awarded to: Jiri Patera, Université de Montréal, for his outstanding contributions to Lie group and Lie algebra theory, with applications to elementary particle and nuclear physics and to quantum chemistry, and more recently for his significant contributions to the mathematical theory of quasicrystals, with applications to condensed matter physics and cryptography.
	The CAP/DCMMP Brockhouse Medal (for Outstanding Experimental or Theoretical Contributions to Condensed Matter and Materials Physics) is awarded to: Mike Thewalt, Simon Fraser University, for his accomplishments in the field of optical spectroscopy of semiconductors. The Medal recognizes both the high quality work that he has consistently produced over a long and still expanding career, and more specifically, the spectacular advances he has made very recently in his studies of isotopically pure silicon. The latter discoveries have set aside decades of misconception concerning intrinsic exciton linewidths in semiconductors, and have led to astoundingly high resolution spectroscopy in which previously unmeasurable fundamental properties, such as the low-temperature limiting behaviour of the energy gap, become clearly visible.
	The CAP Medal for Excellence in Teaching is awarded to: Helmy Sherif, University of Alberta, for outstanding physics teaching at both introductory and advanced levels, and for his exemplary work as a mentor to students and to former students. During his almost twenty years at the University of Alberta Dr. Sherif has played a crucial role in the physics careers of many students. His rapport with students is outstanding, and he takes a personal interest in each student. He was awarded the University of Alberta Faculty of Science Award for Excellent Teaching in 2002.
	The CAP-COMP Peter Kirkby Memorial Medal for Outstanding Service to Canadian Physics is awarded to: Robert Barber, University of Manitoba, for outstanding service, not only to Canadian Physics through his tireless service to the CAP, but also to the community of nuclear physics through his research and organization of conferences, and to the world community of physics through his service to IUPAP. The generosity of his spirit is a source of joy and a model for his colleagues and friends.
	The CAP Herzberg Medal (for outstanding achievement by a physicist aged 40 or less) is awarded to: Victoria Kaspi, McGill University, for her use of instruments at the frontiers of astronomical technology to make pioneering neutron star, pulsar and supernova remnant observations, which have led to significant developments in our understanding of these important and fascinating astrophysical objects.
	The CAP Medal for Achievement in Physics is awarded to: Mike Thewalt, Simon Fraser University, for his far ranging, innovative and insightful experimental studies of the optical properties of semiconductors, including isotopically pure silicon, which have led to significant developments in our understanding of semiconductor physics.

All recipients have been invited to give a plenary lecture during the 2004 CAP Congress at the Delta Hotel, Winnipeg from June 13-16. The medals will be awarded during the Congress banquet to be held on 2004 June 15th.
