A W boson would be the only spin1 particle with a magnetic moment.  Since it has liftime of 3e-35 seconds I doubt anyone has sent W bosons thru an SG; but in theory they should act just like silver atoms or other particles with a magnetic moment. Brent On 4/17/2020 11:56 PM, Alan Grayson

As you probably know, Barbara Tuchman was awarded a Pulitzer prize for The Guns of August (1962). In a later work, The Proud Tower (1966), focused on European history in the two decades preceding WW1, she writes the following in chapter 5 (emphasis mine); JOY, HOPE, SUSPICION—above all,
