As alternatives to the observed K~ -&gt;- 271 decay we consider the processes (i) K~ -+ 271+Y and (ii) K~ -+ K~ magnetic conversion. It is shown that the former process is quite unlikely with the photon energy as suggested from experiment, while the second one is not so unlikely. Also suitable experiments are suggested to observe the processes considered here.
