The concept of heavy particle radioactivity (HPR) is changed to allow emitted particles with Z_e>28 from parents with Z>110 and daughter around 208Pb.

In 1918 Brouwer considered stability of a heavy particle in a rotating vessel. This was the first demon-stration of a rotating saddle trap which is a mechanical analogue for quadrupole particle traps ...

We use the Foldy-Wouthuysen representation to construct Lorentz-invariant interactions. The couplings obtained this way feature a straightforward $1/m$ expansion, which ensures Lorentz invariance orde...
