Announcing a new RHESSI Science Nugget
by Hugh Hudson 28 May '13

28 May '13

No. 201, "Hard X-rays in Descent," by Aidan O'Flannagain and John Brown: A novel test of the thick-target model for hard X-ray emission. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/Hard_X-rays_in_Descent Older Nuggets are available at http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets (the current series, 2008-present), and at http://sprg.ssl.berkeley.edu/~tohban/nuggets/ (the original series, 2005-2008). We publish these at roughly two-week intervals and welcome contributions, which should be related, at least loosely, to RHESSI science.
