The Brazilian Journal of Physics, edited each three months by the Sociedade Brasileira de Física, publishes regular papers and reviews in physics. Articles should be timely and present original and significant results.

Submission of manuscripts
We are no longer accepting printed submissions. Manuscripts should be submitted as a single PDF file (including figures and illustrations). We are still accepting email submissions (to the email address bjp@sbfisica.org.br). However, we invite authors to use our new online submission system. In the preparation of manuscripts, special care should be taken of those symbols which might cause confusion. All references should be sequentially numbered and appear in brackets. They should contain the names and initials of all authors in the following form: [1] A. J. Silva and P. T. Moreira, Braz. J. Phys. 99, 999 (1999). Papers should contain a clear Abstract and some keywords. Authors of accepted manuscripts will be asked to send us a standard TEX source. For additional details please contact Ms. Neusa Martin, at the SBF office, telephone (+55)-11- 3034-0429 (extension 107) or email bjp@sbfisica.org.br.

Refereeing
All submitted contributions will be refereed. The editors reserve the right to reject manuscripts and to require revisions of contributions.

Proofs, page charges and reprints
Authors will receive proofs. There are no page charges, and 25 reprints will be sent, free of charge, to the first or corresponding author.

Correspondence
All correspondence with the editors should contain full reference to the concerned manuscript, including the full title and the names of all authors. Submission letters should include the full mailing address, telephone, fax number, and e-mail address.
